Abstract

PURPOSE:To provide an auto-sampler for avoiding the complexity due to the necessity of preparing a bar-code label corresponding to the content of a sample, and capable of remarkably reducing the errors in the one-to-one correspondence between a position number and the sample. CONSTITUTION:When the bottom part of a sample tube 200 is brought into contact with a pressure sensor 106 to be detected, a work station 300, which has receives a detection signal, let a display part 301 to be in an input queue for a sample name, and consequently, when a keyboard 303 is operated to input the sample name and its return key is depressed, the sample tube 200 is supported by a hold 105 so that the position of the sample tube 200 corresponds directly to the sample name.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an autosampler which is mounted on an analyzer such as a high frequency inductively coupled plasma mass spectrometer and automatically samples a sample. In particular, the sample can be easily identified and the identification name can be easily registered. The auto sampler.

2. Description of the Related Art As is well known, an autosampler is a device that is mounted on an analyzer such as a high frequency inductively coupled plasma mass spectrometer to automatically sample a sample. Conventionally, an autosampler having the following structure has been used. Was widely known.

That is, in the auto sampler as the first conventional example, a number is given in correspondence with the contents of the sample, and then the sample is set in accordance with the position number preset in the auto sampler. Was configured. In addition, the auto sampler as the second conventional example creates a bar code label corresponding to the contents of the sample and attaches it to each sample, and then the bar code is recognized by the auto sampler to analyze the sample. Was configured.

[0004]

However, in the above-mentioned first conventional example, the position number preset in the autosampler and the sample are made to correspond one-to-one with the number corresponding to the contents of the sample. There is a drawback in that such a one-to-one correspondence is complicated and requires human labor, and errors are likely to occur.

Further, the second conventional example has a drawback in that the work of producing the bar code label corresponding to the contents of the sample is extremely complicated and requires a great number of steps. The present invention has been made in view of the drawbacks of the conventional example, and its purpose is to avoid the complexity of creating a barcode label corresponding to the contents of the sample, and to position the sample tube and the sample. It is to provide an auto sampler that can drastically reduce errors when associating names one-to-one.

DISCLOSURE OF THE INVENTION The present invention relates to an autosampler having a bottom portion in which a pressure sensor is embedded, a hole into which a sample tube is inserted, and a shelf portion provided with a hold for pressing the sample tube. A rack, a display section that can display the sample position and sample name, a disk section, and a workstation that has a keyboard while the detection signals of the pressure sensor are transmitted through a signal cable are provided, and the bottom of the sample tube serves as the pressure sensor. When contacted and detected, the workstation receiving the detection signal waits for the input of the sample name on the display unit, and then, when the sample name is input by the keyboard operation and the return key is pressed, the sample tube is set to the above-mentioned state. Supported by the hold so that the position of the sample tube and the sample name have a one-to-one correspondence It is obtained by solving the above problems by forming.

[0007]

The present invention operates as follows. That is, the sample tube containing the sample is erected on the autosampler rack through a hole provided on the shelf of the autosampler rack. Then, the sample tube is slightly pressed from above so that the bottom part of the sample tube contacts the pressure sensor. By doing so, the pressure sensor detects the sample tube and the detection signal is sent to the workstation. In this state, the display unit of the workstation waits for the input of the sample name. Then, when the user operates the keyboard to input the sample name and presses the return key, the sample tube is supported by the hold and the one-to-one correspondence is completed.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory view of the main configuration of an embodiment of the present invention, in which 100 is an autosampler rack, 200 is a sample tube, and 300 is a workstation. Also, the auto sampler rack 100 has a bottom 1
01, side portions 102 and 103, and a shelf portion 104, the hold portion 103 is provided in the shelf portion 104, and the pressure sensor 106 is embedded in the bottom portion 101.

The workstation 300 has a display section 301, a disk section 302 and a keyboard 303, and the keyboard 303 is connected to the main body of the workstation 303 by a cable 304. The pressure signal detected by the pressure sensor 106 of the auto sampler rack 100 is sent to the disk unit 302 of the workstation 300 via the signal cable 400. Although not shown, the hold 105 is adapted to hold a sample tube 200 in response to a color drive signal sent from the workstation 300 according to the drive signal. A commercially available personal computer or the like may be used instead of the workstation 300.

In the embodiment of the present invention having such a structure, the sample tube 200 containing the sample 201 is
The auto sampler rack 100 is passed through a hole (not shown) provided on the shelf 104 of the auto sampler rack 100.
Stand up. Then, the sample tube 200 is slightly pressed from above so that the bottom of the sample tube 200 contacts the pressure sensor 106.

By doing so, the pressure sensor 1
06 detects the sample tube 200, and the detection signal is sent to the workstation 300. In this state, the display unit 301 of the workstation 300 waits for input of a sample name (for example, A in FIG. 1). Next, when the user operates the keyboard 303 to input a sample name and press the return key, a drive signal is issued from the workstation 300 to support the sample tube 200 by the hold 105, and the position number of the sample tube and the sample name have a one-to-one correspondence. Is completed.

The present invention is not limited to the above-mentioned embodiment, and various modifications can be made. For example, a separately registered sample name may be selected and input as the sample name at that time. Further, for example, tap water may be used as a head to generate a serial number, or the sample name may be set to “tap water” and only the number may be manually input.

[0013]

According to the present invention as described in detail above, when setting a sample in the auto sampler, it is troublesome to set a sample number in advance as in the conventional example. There is an advantage that an error-prone process can be omitted. Therefore, according to the present invention, it is possible to avoid the complexity of creating a bar code label corresponding to the contents of the sample and to drastically reduce the error in associating the position number of the sample tube and the sample name one-to-one. Realizes an auto sampler that can.
