Abstract

PROBLEM TO BE SOLVED: To obtain an analyzer in which an artificial mistake due to a handwriting operation and an input operation can be reduced by a method wherein a device which records and reproduces the voice of an operator is operated during a measurement, and additional information is recorded as a voice so as to be reproduced as required. SOLUTION: A loudspeaker 15 which is used as a microphone and a recording instruction key 16 which turns on and off a recording state are provided at a front panel, and the loudspeaker 15 which is used as the microphone is connected to a recording and reproducing device 18 which is built in the side face 17 of a body 11. The body 11 is connected to a personal computer 31 for measured-data processing, by using a communication cable 21, and an analyzed and measured result as measured data which is analyzed and measured by the body 11 as a liquid chromatograph/mass spectrometer is outputted to a printer or the like. A keyboard 32 operates the personal computer 31 so as to execute application software for an installed data processing tool or the like. By this constitution, even while a sample is being analyzed and measured, additional information can be recorded as a voice in such a way that an operator does not turn his eyes away from the sample, and a sudden change in analyzed data is not missed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an analyzer such as a liquid chromatograph mass spectrometer or a gas chromatograph.

[0002]

2. Description of the Related Art Conventionally, for example, in a liquid chromatography mass spectrometer (LCMS), analysis conditions, analysis results, and the like are recorded in a data file.

[0003] In addition, if it is desired to record, as additional information, what an operator observes or notices during analysis / measurement, for example, a characteristic change such as increase / decrease of measurement data or vibration occurs. When recording additional information on things, the information was written by writing on paper or inputting text data from a personal computer keyboard.

[0004]

However, when writing data on paper or inputting data from a keyboard of a personal computer to convert the data, the operator inevitably interrupts the work and keeps an eye on the displayed measurement data. So the peak shape of the data,
In some cases, a change in data such as a change in a spectrum pattern was overlooked, and important processing was lost, or measurement had to be repeated.

[0005]

According to the present invention, in an analyzer, a means for recording and reproducing the voice of an operator is activated during measurement, and additional information is recorded in voice, and this additional information is recorded when necessary. Play information in audio.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an outline drawing and FIG. 2 is a block diagram of a liquid chromatograph mass spectrometer according to the present invention. Reference numeral 11 denotes a main body of the liquid chromatograph mass spectrometer, and a front panel 12 is provided with a microphone / speaker 15 and a recording instruction key 16 for turning on / off a recording state. The microphone / speaker 15 is connected to a recording / reproducing device 18 incorporated in the side surface 17 of the main body 11. In the present embodiment, the recording / reproducing device 18 is configured to be incorporated into the main body 11, but may be a stationary type that is separate from the main body, or may be optional. For this purpose, an audio signal input / output terminal may be provided on the main body 11 and connected by a plug.

The main body 11 is connected to a personal computer 31 for processing measurement data via a communication cable 21 so that data analyzed and measured by the main body 11 of the liquid chromatograph mass spectrometer is transferred. It collects and analyzes measurement data and outputs the measurement results to a printer or the like (not shown). A keyboard 32 attached to the personal computer 31 operates the personal computer 31 and operates an application such as a data processing tool installed on the personal computer 31.

Next, the operation of the liquid chromatograph mass spectrometer according to the present embodiment will be described with reference to FIGS.

First, a sample to be measured is set in the measuring section 20. Then, predetermined measurement conditions are set by the personal computer 31, measurement analysis is performed, and measurement data is collected. The measurement data is transmitted to the personal computer 31 via the communication cable 21.
Is transferred in real time.

On the other hand, the operator views the data being analyzed (chromatograph, mass spectrum, etc.) on the screen of the personal computer 31 and adds a peak shape of the data, a change in the spectrum pattern, and other special notes during the analysis. Information
In the present embodiment, the recording instruction key 16 is pressed to put the recording / reproducing device in the recording state, and the worker speaks to input a voice from the microphone / speaker 15 to record additional information. In addition, by using a recording / reproducing device with a voice input recognition function that can automatically determine a voice input at a predetermined volume or more and put the device in a recording state, an operation of pressing a recording instruction key can be omitted. There is also an effect that it is possible to keep an eye on the measurement data.

After the measurement is completed, for example, at the time of analysis of the measurement data, the reproduction instruction key 19 is pressed to reproduce the recorded additional information, so that the additional information and the measurement result are compared with the operator's voice. And appropriate data analysis can be performed. Also, as an audio data file,
It is also possible to transfer the data to the personal computer 31 and save it as an attached file of the measurement data.

By simultaneously recording the recorded time data, it is possible to grasp the relationship between the recorded additional information and the measurement data. That is, an analyzer for measuring the properties and the amount of a sample, which comprises means for recording and reproducing the voice of the operator in association with the time information of the measurement data, is also an embodiment of the present invention. It is one of the forms.

[0013]

According to the present invention, even during the analysis and measurement of the sample, the additional information can be recorded by recording it by voice, and the information can be recorded while keeping an eye on the sample and observing the data. Can be recorded, so that sudden changes in the analysis data are not missed. In addition, since the apparatus is in the hands-free state, even during the operation of the analyzer, it is possible to record additional information without taking a hand for writing. Furthermore, since there is no transcription by handwriting or input operation from the keyboard, human errors in handwriting and input operation can be reduced.
