Problems solved by technology

However, the tip of the sample loading tube is made of metal. When it is placed in a small beaker, it will tilt at a certain angle due to the gravity of the tip itself, so that air bubbles can easily enter the sample tube of the chromatograph, causing errors in the test results.
And sometimes samples need to be stored at low temperature, so it is necessary to put the beaker in the ice box when loading the sample, which will block the operator's sight, which is not conducive to the smooth progress of the experiment

Embodiment 1

[0021] Such as figure 1 As shown, the chromatographic sampling cup of the present invention is composed of a cup body 1 , a cup cover 2 and a cup cover 9 , a sampling tube 3 , a filter screen 6 , a handle 7 and a base 8 . Wherein the filter screen 6 is stuck in the groove at the maximum diameter of the cup body 1, and the cup body 1 is divided into two spaces on the left and right. The filter screen 6 is a metal mesh with small gaps, which can be disassembled for easy access. In one of the separated spaces, the mouth of the cup body 1 is connected to the interlayer 5 as a whole, and the cup cover 2 is connected to the cup body 1, and the interlayer 5 and the cup body 1 are made of the same material. On its surface, there are holes matching the diameter of the sample pipe 3 . The opening of the sample feeding tube 3 has an extended edge. When the sample adding tube 3 was put into the hole of the interlayer 5, the extended edge of the sample adding tube 3 just stuck on the inte...

Embodiment 2

[0024] The structure of the chromatographic sample cup in this example is basically similar to the structure in Example 1, the only difference is that the clamping device 4 is a long groove 21 arranged on the cup cover 2, one end of the long groove 21 is circular, and the center of the circle is Corresponding to the center of the caliber of the sample tube 3, the other end is the edge of the cup cover 2, and the long groove 21 is provided with a pushable semicircular blocking piece 23, the upper part is a long strip, and the lower part is a short strip, the middle of the long strip and the short strip is connected by the same transverse piece as the width of the long groove 21, as image 3 As shown, the card blocking piece 23 can be taken out from the slot 21.

[0025] Such as Figure 4 As shown, when the chromatographic sample loading cup of the present invention is sampled, the sample loading tube 3 is taken out first, and the sample is added in, and then put into the hole ...

Abstract

The invention relates to a chromatographic sample loading cup which comprises a cup body (1), a cup cover (2) fixed on the cup body (1), a sample loading pipe (3) arranged in the cup body (1) and a clamping and fixing device (4) arranged on the cup cover (2), wherein at least one part of the clamping and fixing device (4) is positioned above an opening of the sample loading pipe (3). When being placed in the chromatographic sample loading cup provided by the invention, a suction head of the sample loading pipe is difficult to lean, so that air bubbles are difficult to generate in a sucker. When a sample needs low temperature, the device can also be used for realizing intercommunication of ice and water to ensure the sample that is loaded in the low-temperature state, ice cubes are very easy to add and the visual line of operators cannot be shaded.

Description

technical field [0001] The invention relates to an instrument for adding samples, in particular to a cup for adding samples to chromatographic instruments. Background technique [0002] At present, when chromatographic instruments are used for biochemical experiments, generally more than 5ml of samples will be loaded through the pump. The operation process is: first put the sample into a beaker with a certain volume, and then put the sample loading tube connected to the pump into the beaker to suck Finally, wrap the mouth of the beaker with aluminum film to prevent contamination, and start the pump to load the sample. However, the tip of the sample loading tube is made of metal. When it is placed in a small beaker, it will tilt at a certain angle due to the gravity of the tip itself, so that air bubbles can easily enter the sample loading tube of the chromatograph, causing errors in the detection results. Moreover, sometimes samples need to be stored at low temperature, so ...
