Description

  The present invention relates to an analyzer such as a thermal analyzer or an X-ray analyzer.

  The thermal analyzer is an apparatus that measures changes in physical properties, weights, and the like of a sample while changing the temperature of the sample, and analyzes the sample based on the measurement result. An X-ray analyzer is an apparatus that analyzes the structure of a sample by measuring the intensity of diffraction lines, scattered rays, and the like generated from the sample when the sample is irradiated with X-rays.

  Among these analyzers, there is conventionally known an apparatus that displays a measurement result on a screen and performs an analysis based on the screen display (see, for example, Patent Document 1). In this document, a two-dimensional image is displayed on the screen (FIG. 3), or a three-dimensional image is planarly displayed on the screen using contour display (FIGS. 4 and 7).

JP 2001-318063 (Pages 6-7, FIG. 3, FIG. 4, FIG. 7)

  As disclosed in Patent Document 1, it is conventionally known to display each change of three parameters three-dimensionally on a screen. In recent years, for example, as shown in FIG. 15, a three-dimensional image is displayed three-dimensionally rather than planarly. However, even if it is a planar three-dimensional display or a three-dimensional three-dimensional display, the conventional three-dimensional display is used only for observing the measurement result. No input processing could be performed on the dimension display. Thus, in the conventional analyzer, the three-dimensional display has not been fully utilized.

  The present invention has been made in view of the above-mentioned problems in the conventional apparatus, and an object of the present invention is to make it possible to more effectively utilize the measurement results of the analysis apparatus displayed three-dimensionally on the screen. To do.

  The analysis apparatus according to the present invention includes a measurement unit that acquires measurement data regarding three parameters, an image display unit that displays an image on a screen based on the image data, and the three parameters as linear coordinate axes. Three-dimensional stereoscopic image display means for displaying the measurement data as a stereoscopic image on three-dimensional coordinates, and the measurement data relating to the two parameters on two-dimensional coordinates using two of the three parameters as orthogonal coordinate axes. Two-dimensional image display means for displaying, an input image for inputting data indicating at least one coordinate axis of the three coordinate axes and a coordinate value on the coordinate axis is displayed on the screen and the input Input image processing means for reading coordinate axes and coordinate values input to the image, and the three-dimensional stereoscopic image display means includes the input image And displaying by a line coordinate value input on the 3D stereoscopic image using.

  In the above configuration, the three parameters are selected from various parameters. For example, considering the case of performing mass analysis of a gas generated from a sample whose temperature changes, the sample temperature, the mass number of the generated gas, and the ionic strength of the generated gas can be considered as three parameters. Considering the case of analyzing a sample by detecting diffraction lines, scattered rays, etc. generated from the sample when the temperature changing sample is irradiated with X-rays, sample temperature, diffraction angle (2θ) ) And diffraction line intensity.

  According to the analysis apparatus of the present invention, the measurement result is displayed on the screen as a three-dimensional stereoscopic image instead of a three-dimensional planar image displayed using the contour display. The analyst can therefore perform a quick and accurate analysis.

  Further, the analyst can input any one coordinate axis and any coordinate value on the axis through the input image displayed on the screen. The input coordinate values are displayed as input lines on the three-dimensional stereoscopic image. For example, three parameters of sample temperature, generated gas mass number, and generated gas ionic strength are selected as coordinate axes, and the mass number axis and coordinate value “α” on that axis are input. If so, an input line is displayed at the mass number “α” on the three-dimensional stereoscopic image. For this reason, the analyst can immediately and accurately determine the ion intensity with which the gas having the mass number “α” is generated when the sample temperature is variously changed with reference to the input line.

  For example, if the temperature axis and the coordinate value “β” on the three parameters of the sample temperature, the mass number of the generated gas, and the ion intensity of the generated gas are input, the three-dimensional stereoscopic image is displayed. An input line is displayed at the temperature “β”. For this reason, the analyst can immediately and accurately determine the number of ionic strengths of gases having various mass numbers when the temperature is “β” with reference to the input line.

  As described above, according to the present invention, an arbitrary coordinate axis and an arbitrary coordinate value on the axis can be input to the three-dimensional stereoscopic image displayed on the screen, and the input coordinate value can be input to the three-dimensional stereoscopic image. Since it is possible to display with the input line above, the three-dimensional stereoscopic image can be used very effectively.

  Next, in the analysis apparatus according to the present invention, the two-dimensional image display means displays two-dimensional coordinates having two coordinate axes other than the coordinate axes input using the input image as orthogonal coordinate axes, and It is desirable that the measurement data relating to the two coordinate axes and corresponding to the input coordinate values is displayed on the two-dimensional coordinates.

  According to this configuration, when one coordinate axis and a coordinate value on the axis are input by the input image processing means, the input line corresponding to the coordinate value is displayed on the three-dimensional stereoscopic image, and at the same time, 2 A two-dimensional image corresponding to the coordinate value is displayed as a three-dimensional image. For example, if the mass number axis of the temperature axis, mass number axis, and ionic strength axis is input as one coordinate axis, and the mass number “41” is input as a coordinate value, the mass is displayed on the three-dimensional stereoscopic image. An input line parallel to the temperature axis is displayed at the number “41”, and at the same time, a two-dimensional coordinate (ie, mass chromatogram) having a temperature axis other than the mass number axis and an ion intensity axis as orthogonal axes. Above, the relationship between the temperature change of the gas having the mass number “41” and the ion intensity at each temperature is displayed as a two-dimensional image.

  The analyst can compare and observe both the three-dimensional stereoscopic image and the mass chromatogram on which the input line is displayed. Also, if the mass number is changed from “41” on the three-dimensional stereoscopic image, that is, the input line is translated from “41”, the graph which is the content of the two-dimensional image changes its mass number (ie, The input line changes on the three-dimensional stereoscopic image. The analyst can perform analysis while simultaneously viewing the parallel movement of the input line on the three-dimensional stereoscopic image and the change in the graph of the two-dimensional image, and therefore perform a very accurate analysis in a short time. Can do. For example, the quantitative analysis of gas performed by obtaining the area of the mass chromatogram can be performed accurately in a short time.

  Furthermore, the analyst can input the temperature axis as one coordinate axis instead of or in addition to inputting the mass number axis of the temperature axis, mass number axis, and ionic strength axis, for example. At the same time, for example, the temperature “370 ° C.” can be input as a coordinate value. In this case, instead of or in addition to displaying an input line parallel to the temperature axis at the mass number “41” on the three-dimensional stereoscopic image, the mass number axis at the temperature “370 ° C.”. A second input line parallel to is displayed. At the same time, the relationship between the temperature change of the gas having the mass number “41” and the ion intensity at each temperature on a two-dimensional coordinate (ie, mass chromatogram) having the temperature axis and the ion intensity axis as orthogonal coordinate axes. Instead of or in addition to being displayed as a two-dimensional image, the mass number of a gas having a temperature of “370 ° C.” on two-dimensional coordinates (ie, mass spectrum) having a mass number axis and an ion intensity axis as orthogonal coordinate axes. The relationship between the change in the ion intensity and the change in the ion intensity is displayed as a two-dimensional image.

  An analyst can perform a qualitative analysis (ie, an analysis of what gas is generated) by evaluating the mass spectrum. In this case as well, the analyst can perform the analysis while simultaneously viewing the parallel movement of the input line on the 3D stereoscopic image and the change in the graph of the 2D image. Can be done in time.

  Next, the analysis apparatus according to the present invention displays the measurement data as a planar three-dimensional image on three-dimensional coordinates in which two of the three parameters are orthogonal coordinate axes and the other one parameter is displayed as a contour line. 3D plane image display means for performing, and further, the 3D plane image display means uses coordinate values input using the input image as input lines on the plane 3D image. It is desirable to display. Thus, if a three-dimensional planar image is also displayed in addition to a three-dimensional stereoscopic image, the generation distribution of the generated gas species can be grasped.

  Next, in the analysis apparatus according to the present invention, it is preferable that the input image processing means displays a moving element moving in the input image as an image, and reads the coordinate value according to the position of the moving element. Generally, various configurations are conceivable as means for inputting various data to the analyzer. For example, it is conceivable to perform input using a keyboard. An input device configured with a screen display and a mouse-type input tool is also conceivable. An input device configured with a screen display and a touch panel is also conceivable. However, as in the aspect of the present invention, if input is performed using a mover that moves within an image, input processing can be performed easily and quickly.

  Next, in the analyzer according to the present invention, the measuring means is a mass analyzing means for measuring a mass number of a gas generated from a temperature-changing sample and an ion intensity of the gas, and the three parameters are a sample temperature. The mass number of the generated gas and the ionic strength of the generated gas are desirable. If a three-dimensional stereoscopic image and a two-dimensional image are displayed according to the present invention with respect to these three parameters, an accurate analysis can be performed regarding the generated gas analysis.

  Next, in the analyzer according to the present invention in which the sample temperature, the mass number of the generated gas, and the ion intensity of the generated gas are the three parameters, the three-dimensional stereoscopic image display means includes the sample temperature axis and the generated gas mass number axis. It is desirable that the plane coordinates are constituted by the above and the generated gas ion intensity axis is a solid axis. Further, in the analyzer according to the present invention in which the sample temperature, the mass number of the generated gas, and the ion intensity of the generated gas are the three parameters, the two-dimensional image display means generates the generated gas ion intensity with the sample temperature axis as the horizontal axis. Displays either or both of the mass chromatogram, which is a two-dimensional coordinate with the axis as the vertical axis, and the mass spectrum, which is a two-dimensional coordinate with the generated gas mass number axis as the horizontal axis and the generated gas ion intensity axis as the vertical axis. It is desirable to do.

  Hereinafter, an analyzer according to the present invention will be described based on embodiments. Of course, the present invention is not limited to this embodiment. In the drawings, the components may be shown in different ratios from the actual structure as necessary.

  FIG. 1 shows an embodiment of an analyzer according to the present invention. In this embodiment, three types of measurements, that is, mass spectrometry, TG (Thermogravimetry) measurement, and DTA (Differential Thermal Analysis) measurement are performed, and measurement data obtained by these measurements is analyzed. The present invention is applied to an apparatus.

  In FIG. 1, an analysis apparatus 1 is a computer including a CPU (Central Processing Unit) 2, a RAM (Random Access Memory) 3, a ROM (Read Only Memory) 4, a memory 5, and a bus line 6 connecting them. Has a control system. The analyzer 1 also includes the following devices as external devices connected to the bus line 6, that is, a mass spectrometer 9, a TG measurement device 10, a DTA measurement device 11, an input device 12, an image display device 13, and And a printer 14. The image display device 13 can be configured using, for example, a CRT (Cathode-ray Tube) display, a flat panel display, or the like. The printer 14 can be constituted by, for example, an electrostatic transfer printer, an inkjet printer, or any other printer. Further, the input device 12 can be configured using, for example, a keyboard, a mouse type input device, a touch panel type input device, or the like.

  The CPU 2 functions as an arithmetic / control device that performs operations according to programs and controls the operations of the RAM 3, ROM 4, and memory 5. Further, the CPU 2 functions as a function realizing unit that realizes a predetermined function in cooperation with various program software, RAM 3, and ROM 4 stored in the memory 5.

  In the case of this embodiment, the mass spectrometer 9, the TG measurement device 10, and the DTA measurement device 11 are configured as one measurement system as shown in FIG. This measurement system includes a balance beam 17a that supports a standard material S0 that is a material that does not change its physical properties even when the temperature fluctuates, a balance beam 17b that supports a sample S1 to be measured, a standard material S0, and a sample S1. And a heater 19 for heating the inside of the casing 18. The heater 19 is a heating device that generates heat by energization and heats the inside of the casing 18, and as shown in the graph Gt, the temperature in the casing 18 is controlled to rise linearly with the passage of time.

  The TG measurement device 10 measures the weight difference (ΔG) between the standard material S0 and the sample S1 by detecting the movement of the balance beam 17a and the balance beam 17b, and a signal indicating the weight difference ΔG and the weight difference are obtained. A signal indicating the temperature (T) when it occurs is output. The DTA measuring device 11 detects the temperature of the standard substance S0 and the temperature of the sample S1, and outputs a signal indicating the temperature difference (ΔT) and a signal indicating the temperature (T) when the temperature difference occurs. . The mass spectrometer 9 is connected to the inside of the casing 18 by a gas pipe 20. When any gas is generated from the sample S1 whose temperature changes, the gas is introduced into the mass spectrometer 9 through the gas pipe 20. The mass spectrometer 9 measures the mass number (m / z) and ionic strength (I) of the introduced gas and outputs a signal indicating them.

  In the memory 5 of FIG. 1, a mass analysis program 23 that controls mass spectrometry measurement performed using the mass spectrometer 9, and a TG measurement program 24 that controls TG measurement performed using the TG measurement apparatus 10. The DTA measurement program 25 for controlling the DTA measurement performed using the DTA measurement device 11 is stored in each predetermined area. In addition, (m / z, I) measurement data obtained as a result of mass spectrometry measurement, (T, ΔG) measurement data obtained as a result of TG measurement, or DTA measurement result (T, A file 26 for storing measurement data (ΔT) is provided in a predetermined area of the memory 5.

  In the measurement data file 26, for example, data of mass spectrometry measurement results as shown in FIGS. 5 and 6 are stored. 5 and FIG. 6 show one data file separately for convenience because of the size of the page. Actually, the data shown in FIG. 6 is stored after the data shown in FIG. . In this embodiment, the temperature of the sample is controlled so as to rise linearly, and therefore the temperature (T) and time (t) in FIG. 5 are in a one-to-one relationship. Therefore, in data processing, temperature (T) may be used or time (t) may be used.

  In FIG. 1, the memory 5 stores an analysis program 27, a 2D / 3D image generation program 28, and an input image processing program 29. The analysis program 27 is program software that is activated when the analyst performs various analyzes based on the measurement data stored in the measurement data file 26. Data obtained by the analysis can be stored in the analysis data file 37 in the memory 5. The 2D / 3D image generation program 28 is a program for displaying the measurement data stored in the measurement data file 26 on the screen of the image display device 13 in the form of either or both of a two-dimensional image and a three-dimensional image. It is soft.

  Here, the two-dimensional image is an image in which data is displayed by lines in plane coordinates defined by the two axes of the horizontal axis Xa and the vertical axis Xb, as in the graph shown by the arrows Gc and Gd in FIG. . In addition, there are two types of three-dimensional images: a three-dimensional stereoscopic image indicated by symbol Ga and a three-dimensional plane image indicated by symbol Gb. The three-dimensional stereoscopic image Ga is an image in which data is displayed as a three-dimensional image on three-dimensional coordinates represented by three linear coordinate axes of the horizontal axis Xa, the vertical axis Xb, and the solid axis Xc. The three-dimensional plane image Gb is an image that represents the data amount in the direction perpendicular to the paper surface by displaying the data in a contour line within the plane coordinates defined by the horizontal axis Xa and the vertical axis Xb.

  In the present embodiment, the 2D / 3D image generation program 28 displays the 3D stereoscopic image Ga in a region slightly wider than the left half of the display window, and displays the 3D planar image Gb in the upper right region. Although the image data for displaying the two-dimensional images Gc and Gd in the middle region and the lower region on the right side is generated, the arrangement of these images in the screen 32 can be variously changed as required.

  The 2D / 3D image generation program 28 in FIG. 1 includes a two-dimensional image generation unit that generates video display memory (V-RAM) data for displaying the data in the measurement data file 26 as a two-dimensional image, and a measurement data file. A three-dimensional plane image generation unit for generating video display memory (V-RAM) data for displaying the data in the data 26 as a three-dimensional plane image, and for displaying the data in the measurement data file 20 as a three-dimensional stereoscopic image. Each image generation unit is called a three-dimensional stereoscopic image generation unit that generates video display memory (V-RAM) data.

  The input image processing program 29 is program software for displaying an input image indicated by a symbol Ge in the main screen of FIG. This input image Ge includes images of the temperature axis moving element 30 and the mass number axis moving element 31. A pointer (not shown) moved by the mouse-type input tool can be made to coincide with these movers, and further, the pointer and the mover can be translated left and right by operating the mouse-type input tool. Then, the input image processing program 29 recognizes that coordinate values on each coordinate axis have been input based on the positions of the movers. Specifically, it is recognized that the coordinate value on the temperature coordinate axis Xa in the three-dimensional stereoscopic image Ga and the three-dimensional plane image Gb is input based on the position of the temperature axis moving element 30. Further, it is recognized that the coordinate value on the mass number coordinate axis Xb in the three-dimensional stereoscopic image Ga and the three-dimensional plane image Gb is input based on the position of the mass number axis moving element 31.

  The illustrated input image Ge is an example of an image for processing input data, and the image content of the input image Ge can be variously modified as necessary. In short, it is only necessary to be able to change the positions of the movers 30 and 31 and to read the positions of these movers. When the temperature (T) is input by the mover 30 and the mass number (m / z) is input by the mover 31 in the input image Ge of FIG. 7, the analysis program 27 of FIG. It is stored in the input value storage file 33 of FIG.

  In FIG. 1, a qualitative analysis program 34 is stored in the memory 5. This qualitative analysis program 34 is a mass spectrum obtained based on the measurement data (m / z, I) and temperature data (T) obtained by the mass spectrometer 9 (that is, the mass number of the generated gas at a specific temperature). This is program software that is activated when performing a qualitative analysis (that is, an analysis for determining the type of gas contained in the generated gas) based on each ion intensity). The qualitative analysis program 34 performs analysis by comparing a mass spectrum to be analyzed with a reference mass spectrum. A plurality of reference mass spectrum data is stored in a library data file 39 in the memory 5. Stored in advance.

  A still processing program 35 is stored in the memory 5. In the present embodiment, in FIG. 7, by operating the temperature axis moving element 30 and the mass number axis moving element 31, the measurement data displayed on the two-dimensional image Gc and the two-dimensional image Gd are changed in temperature and mass number. Various parameters can be changed. In this case, if the data content displayed last time is completely removed every time the data content is changed, it is troublesome because the same operation as the previous time must be performed again when it is desired to redisplay the data content. In view of this, in the present embodiment, the data contents of the two-dimensional images Gc and Gd once displayed are stored in the still data file 36 in the memory 5, and the data is displayed on the screen 32 of FIG. 7 at a desired timing. Can be read. The still processing program 35 is program software for performing such data processing, which will be described later in detail.

  A multiple drawing program 38 is stored in the memory 5 of FIG. In this embodiment, the mass analysis result (T, m / z, I) using the mass spectrometer 9, the TG measurement result (T, ΔG) using the TG measurement device 10, and the DTA measurement device 11 are used. Each measurement data of the DTA measurement result (T, ΔT) is obtained independently. The multiple drawing program 38 is program software for drawing, that is, displaying, the measurement data obtained uniquely on one coordinate.

  Hereinafter, the operation of the analyzer having the above configuration will be described with reference to the flowcharts shown in FIGS. In steps S1 to S5 in FIG. 3, TG measurement, DTA measurement, and mass spectrometry measurement are performed as necessary. When the measurement is completed, measurement data (T (temperature), m / z (mass number), I (ion intensity)) obtained by mass spectrometry measurement, measurement data (T, ΔG) obtained by TG measurement , And (T, ΔT) measurement data obtained by DTA measurement are stored in the measurement data file 26 of FIG. 1 in the form of a data table as shown in FIGS. 5 and 6, for example. (Step S6 in FIG. 3). 5 and 6 mainly show only measurement data related to mass spectrometry, the measurement data related to TG measurement and DTA measurement are also stored in the same format.

  By the way, in this embodiment, the analyzer 1 of FIG. 1 has the mass spectrometer 9, the TG measuring device 10, and the DTA measuring device 11, and the measurement data obtained as a result of the actual measurement by each of these measuring devices is obtained. The data is sequentially stored in the measurement data file 26. However, instead of this, the measurement data obtained by the measurement performed in another place in advance is transferred to the data file 26 via the bus line 6 and stored, and the stored measurement data is used for analysis. You can also.

  Next, when an instruction to perform analysis processing is given by the analyst through the input device 12 of FIG. 1, the flow of control enters the routine of analysis processing in step S8 of FIG. When entering the analysis processing routine, in step S11 of FIG. 4, the data (T, m / z, I, ΔT, ΔG) obtained from one of the data stored in the measurement data file 26 of FIG. ) Data is read out. In step S12, the data stored in the input (m / z, T) file 33 in FIG. 1 is read. This data is data that was input and held in the previous analysis. In this case, m / z = 41 and T = 376.0 ° C. are read out.

  Next, the 2D / 3D image generation program 28 in FIG. 1 is started, and the 3D stereoscopic image data, 3D plane image data, 2D image data, and input image data are updated in steps S13 to S15 in FIG. Each image data is generated, the image data is transmitted to the image display device 13 of FIG. 1, and each image is displayed on the screen. Specifically, in FIG. 7, the three-dimensional stereoscopic image Ga is displayed in the left region of the screen 32, the input image Ge is displayed in the upper region, and the three-dimensional planar image Gb is displayed in the upper left portion of the screen 32. The mass chromatogram Gc, which is a two-dimensional image, is displayed on the left middle, and the mass spectrum Gd, which is a two-dimensional image, is displayed on the lower left.

  In the present embodiment, the 2D / 3D image generation program 28 can also display a TG-DTA curve that is a two-dimensional image as shown in FIG. The window display including the TG-DTA curve can be displayed over the window display of the main graph shown in FIG. 7 in accordance with an instruction from the analyst.

  The three-dimensional stereoscopic image Ga in FIG. 7 represents the characteristics of (T, m / z, I) relating to one sample in the form of a three-dimensional stereoscopic image. The three-dimensional stereoscopic image Ga is formed on three-dimensional coordinates defined by the horizontal axis Xa, the vertical axis Xb, and the solid axis Xc. Here, the horizontal axis Xa is the temperature (T) axis (that is, the time axis), and the vertical axis Xb that forms the plane coordinates in cooperation with the horizontal axis Xa is the mass number (m / z) axis. The solid axis Xc is an ionic strength (I) axis. The three-dimensional stereoscopic image Ga is formed by plotting a plurality of (T, m / z, I) data read from the measurement data file 26 of FIG. 1 on the above three-dimensional coordinates.

  The sample currently considered has five peaks P1, P2, P3, P4 and P5 as shown in FIG. From the viewpoint of ionic strength, P4> P3> P5> P1> P2. In this embodiment, the peak waveform is displayed in gradation so that the concentration increases as the ionic strength increases from 0 (zero) so that the ionic strength can be easily recognized visually. Alternatively, from the ion intensity = 0 (zero), the first stage area is displayed in “blue”, the second stage area is displayed in “green”, and the third stage is displayed in “yellow”. It is also possible to make the identification of the magnitude of the ionic strength easier by performing color-coded display such as displaying the fourth row in “red”.

  The two-dimensional image data generated in step S14 in FIG. 4 is for displaying the two-dimensional images Gc and Gd in FIG. 7. This two-dimensional image data is read in step S12 in FIG. / Z, T). That is, in step S12, m / z = 41 and T = 376.0 ° C. are read as the previous input values, so in step S14, data of (T, I) relating to m / z = 41 is read. Thus, two-dimensional image data corresponding to the mass chromatogram Gc of FIG. 7 is generated. Further, (m / z, I) data relating to T = 376.0 ° C. is read, and two-dimensional image data corresponding to the mass spectrum Gd of FIG. 7 is generated.

  Further, in the three-dimensional image data generation step of step S13, as shown in FIG. 8, corresponding to the input value of (m / z, I), that is, corresponding to m / z = 41 and T = 376.0 ° C. Thus, image data for displaying the input lines L1 and L2 which are straight lines is generated. The input line L1 is a straight line that passes through the coordinate value of m / z = 41 and is parallel to the temperature axis Xa. On the other hand, the input line L2 is a straight line that passes through the coordinate value of T = 376.0 ° C. and is parallel to the mass number axis Xb.

  Of course, the input line L1 shows the waveform of the mass chromatogram Gc (mass chromatogram of a gas having a mass number of 41) in FIG. Further, the input line L2 is not limited to the waveform of the mass spectrum of FIG. 7 (the generated gas spectrum at a temperature of 376.0 ° C.). An analyst who observes a mass chromatogram or a mass spectrum directly performs an analysis while looking at the mass chromatogram Gc or the mass spectrum Gd. Analysis is performed in consideration of not only the mass chromatogram Gc of the number but also the mass chromatogram Gc of a different mass number, or analysis is performed in consideration of the mass spectrum Gd of a different temperature as well as the mass spectrum Gd of the corresponding temperature. There are things to do.

  In such a case, in the conventional image display method in which only the two-dimensional images Gc and Gd are displayed on the screen, mass chromatograms and mass spectra under various conditions are alternately displayed after a troublesome operation. However, according to the present embodiment in which the two-dimensional images Gc and Gd and the three-dimensional images Ga and Gb are simultaneously displayed on one screen 32, the three-dimensional images Ga, Since the two-dimensional images Gc and Gd can be observed while observing Gb, a highly reliable analysis can be performed in a short time.

  In the present embodiment, the mass number (m / z) of the displayed mass chromatogram Gc is displayed as the input line L1 on the three-dimensional stereoscopic image Ga and the three-dimensional planar image Gb. The temperature (T) of the mass spectrum Gd is displayed as the input line L2 on the three-dimensional stereoscopic image Ga and the three-dimensional planar image Gb. Therefore, the analyst can accurately grasp the mass chromatogram Gc on the three-dimensional images Ga and Gb by the input line L1, and further can accurately grasp the mass spectrum Gd on the three-dimensional images Ga and Gb by the input line L2. For this reason, a more accurate analysis can be performed.

  Furthermore, in this embodiment, the coordinate value of the input line L2 on the temperature axis Xa is determined by the position of the temperature axis moving element 30 in the input image Ge in FIG. If the analyst moves the position of the mover 30 by operating the mouse, “YES” is determined in step S18 of FIG. 4, and new image data is generated in steps S13 to S16. As a result, the input line L2 is displayed. It is possible to perform display that is translated along the temperature axis Xa. The coordinate value of the input line L1 on the mass number axis Xb is determined by the position of the mass number axis moving element 31. If the position of the mass number axis moving element 31 is moved by a mouse operation, the same applies. With this image processing, it is possible to perform display in which the input line L1 is translated along the mass axis Xb.

  If the input line L1 is translated along the mass number axis Xb on the three-dimensional stereoscopic image Ga, mass chromatograms of the corresponding mass numbers are displayed one after another on the mass chromatogram Gc. As a result, the analyst can appropriately specify a desired mass chromatogram in a short time, and as a result, the quantitative analysis performed based on the area of the mass chromatogram can be performed very accurately.

  If the input line L2 is translated along the temperature axis Xa on the three-dimensional stereoscopic image Ga, mass chromatograms of the corresponding temperatures are displayed one after another on the mass spectrum Gd. Thereby, the analyst can appropriately specify a desired mass spectrum in a suitable short time, and as a result, a qualitative analysis performed using the mass spectrum can be performed very accurately.

  Next, in this embodiment, an instruction for rotating the three-dimensional stereoscopic image Ga on the screen can be performed by an appropriate operation using a mouse, a keyboard, or the like. When this instruction is given, “YES” is determined in step S17 of FIG. 4, and the process returns to step S13 to newly generate three-dimensional image data based on the designated viewpoint. As a result, as shown in FIG. Display that rotates the three-dimensional stereoscopic image Ga can be performed. Thus, the analyst can observe the three-dimensional stereoscopic image Ga from a desired angle, and can perform an accurate analysis.

  In FIG. 7, a three-dimensional stereoscopic image Ga, a three-dimensional planar image Gb, and two-dimensional images Gc, Gd are displayed based on the measurement data (T, m / z, I) obtained for a certain sample. If the measurement data of (T, m / z, I) obtained for the different samples by the CPU 2 in FIG. 1 is read from the measurement data file 26, the three-dimensional stereoscopic image Ga, the three-dimensional planar image Gb, The two-dimensional images Gc and Gd are obtained, for example, as shown in FIG. In FIG. 9, the mass number 44 is selected by the mover 31 and the temperature 639.2 ° C. is selected by the mover 30 for a sample different from the case of FIG. 7. In the three-dimensional stereoscopic image Ga and the three-dimensional plane image Gb, the input line L1 is displayed at the coordinate value 44 of the mass number axis Xb, and the input line L2 is displayed at the coordinate value 639.2 ° C. of the temperature axis Xa. Has been. Further, when viewing the regions of the two-dimensional images Gc and Gd, a mass chromatogram Gc having a mass number of 44 is displayed, and a mass spectrum Gd having a temperature of 639.2 ° C. is displayed.

  In the present embodiment, the analyst can perform a qualitative analysis of the sample using the mass spectrum Gd of FIG. This qualitative analysis compares the mass spectrum Gd of a sample whose composition is unknown as a result of measurement with a standard mass spectrum obtained in advance for a substance whose composition is known, and determines the composition of the unknown sample. It is an analysis to do. An analyst who wants to perform qualitative analysis instructs the start of qualitative analysis by appropriately operating the input device 12 of FIG. Then, it determines with YES by step S19 of FIG. 4, and enters into the processing routine of qualitative analysis of step S20.

  Then, the CPU 2 in FIG. 1 reads appropriate library data from the library data file 39 in the memory 5 and displays the library data in the lower area of the screen 32 in FIG. Further, the main part of the mass spectrum Gd (actual measurement data) in FIG. 7 is displayed in the upper region as indicated by reference numeral Q3. Further, the image Q2 displayed together so that the actual measurement data Q3 and the library data Q1 are easily compared is displayed in the middle area. The analyst can determine the composition of the sample by observing the comparative image. Further, the CPU can determine the degree of coincidence between the actual measurement data Q3 and the library data Q1 by calculation according to a predetermined procedure as necessary. The analyst can also perform a qualitative analysis in consideration of the degree of coincidence.

  Next, in this embodiment, the analyst can execute the still process by operating the input device 12 of FIG. In the present embodiment, the contents of the mass chromatogram Gc and the mass spectrum Gd can be variously updated by operating the temperature axis moving element 30 and the mass number axis moving element 31 in FIG. At this time, if the data content displayed last time is completely removed every time the data content is changed, the same operation as the previous time must be performed again when it is desired to redisplay the data content, which is troublesome. In view of this, in this embodiment, the data contents of the once displayed mass chromatogram Gc and mass spectrum Gd can be easily redisplayed at an arbitrary timing. Such processing is still processing.

  When the still process is instructed by the analyst, YES is determined in step S21 in FIG. 4, the flow of control enters the still process routine in step S22, and the CPU 2 in FIG. 1 starts the still process program 35. Then, a predetermined image signal is transmitted to the image display device 13 of FIG. 1, and a still window 42 is displayed in the left area of the screen 32 as shown in FIG. When the still processing has not been performed so far, or after the apparatus has been initialized, the still window 42 is blank and no information is contained therein. On the other hand, when still processing has been performed in the past, an identification mark M corresponding to the still processing performed in the past is displayed in the still window 42.

  Assume that the analyst intends to re-display the mass chromatogram Gc displayed on the screen 32 at the current time and temporarily stores it in the still window 42. In this case, the analyst designates the area of the mass chromatogram Gc by double-clicking the mouse operation, or, as indicated by the arrow A, drags and drops the mouse input tool between the mass chromatogram Gc and the still window 42. I do. Then, the CPU 2 in FIG. 1 transfers (m / z, T, I) data (m / z is one value) displayed as the mass chromatogram Gc into the still data file 36, and there To remember. At that time, the CPU 2 converts the image of the mass chromatogram Gc displayed on the screen 32 of FIG. 11 into an image data file, for example, a bitmap (BMP) or JPEG, and as indicated by a symbol D in FIG. The image data is stored in correspondence with the data contents. 11 is displayed as an identification mark M in the still window 42 of FIG.

  The imaged identification mark M is an image of the image of the mass chromatogram Gc as it is. Therefore, as soon as the analyst looks at the identification mark M, what the stored contents are like. Can be determined quickly and reliably.

  When the analyst wants to temporarily store the mass spectrum Gd currently displayed on the screen 32, for example, by dragging and dropping the mass spectrum Gd toward the still window 42 as indicated by the arrow B, The data content of the mass spectrum Gd can be stored in the still data file 36 of FIG. 1, and at the same time, the image of the mass spectrum Gd can be stored as an identification mark M in the form of image data.

  Thereafter, when the analyst wants to redisplay the data stored in the still window 42 for analysis or the like, the identification mark M that is desired to be redisplayed among the identification marks M displayed in the still window 42 is indicated. For example, double-click. For example, when it is desired to redisplay the data of the mass chromatogram M1 displayed in the still window 42 in FIG. 12, the identification mark M1 is double-clicked in FIG. Then, the corresponding (m / z, T, I) data stored in the still data file 36 in FIG. 1 is read, further converted into two-dimensional image data, transmitted to the image display device 13, and The image is redisplayed on the screen as indicated by reference numeral Gc ′ in FIG. The analyst can perform a desired analysis based on this display, for example, calculate the area and perform a quantitative analysis.

  Next, the analyst can execute multiple drawing processing by operating the input device 12 of FIG. When this processing is performed, YES is determined in step S23 of FIG. 4, and the multiple drawing processing routine of FIG. 1 is started by entering the multiple drawing processing routine of step S24. Then, instead of the screen of the mass spectrometry system described so far, data of another measurement system, for example, measurement data of TG-DTA measurement as shown in FIG. 13 is displayed as a graph.

  If the analyst wishes to display the mass chromatogram Gc or the mass spectrum Gd on the TG-DTA measurement result, an appropriate instruction such as a double click operation is given to the mass chromatogram Gc or the mass spectrum Gd. Do. Then, as shown in FIG. 14, the mass chromatogram Gc and the mass spectrum Gd are displayed so as to overlap the TG-DTA diagram. The analyst can perform more detailed analysis by observing the synthesized graph.
