Description

Technical Field

[0001] The utility model relates to the technical field of chromatographs, in particular to a chromatograph auxiliary device. Background Art

[0002] Liquid chromatograph is an instrument that uses the difference in the distribution ratio of the mixture between liquid and solid or between two immiscible liquids to separate the mixture first and then analyze and identify it. Liquid chromatographs are divided into liquid-liquid chromatography and liquid-solid chromatography according to whether the stationary phase is liquid or solid. Modern liquid chromatographs are composed of high-pressure infusion pumps, injection systems, temperature control systems, chromatographic columns, detectors, signal recording systems, etc. Compared with classic liquid column chromatography devices, it has the characteristics of high efficiency, rapidity, and sensitivity.

[0003] The publication number in the existing public technology is: CN219245468U. An auxiliary device of a liquid chromatograph comprises a sample bottle, wherein the lower end of the sample bottle is provided with a base, the upper end of the base is fixedly installed with a fixing block, the upper end of the fixing block is provided with a movable seat, the lower end of the movable seat is fixedly installed with a cylinder, and the telescopic end of the cylinder is fixedly installed with an injection needle tube, the upper end of the base is provided with a first placement groove, and the lower end of the first placement groove is symmetrically provided with a second placement groove. The utility model is provided with a T-shaped slide groove and a T-shaped slide block, and the T-shaped slide groove and the T-shaped slide block are used in coordination, so that the movable seat can be moved during installation to better place the sample bottle, firstly, the sample bottle can be placed on the carrying plate, and the weight of the sample bottle itself will cause the carrying plate to move downward, so that the clamping plate can clamp and fix the sample bottle, and sample bottles of different sizes can be fixed. The utility model has the characteristics of strong practicality and good versatility.

[0004] However, the above patent still has certain disadvantages when used: although the clamping plate can automatically clamp and fix the sample bottle, the liquid inside will continue to decrease as the test proceeds, thereby reducing the weight of the sample bottle. At this time, the downward movement of the support plate will become smaller, causing the clamping plate to move away from the sample bottle. At this time, the sample bottle will lose its grip, resulting in reduced stability, which is not conducive to detection and use. Moreover, during operation, a group of sample bottles must be used up before subsequent settings can be carried out, so the operation efficiency is low and the use effect is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
