Problems solved by technology

When liquid chromatography or gas chromatography is used, the first step is to use a micro-syringe to inject the sample. The micro-syringe is equipped with a scale. Since the volume of the micro-syringe itself is small, the scale value marked on it is smaller. It is difficult to read when using, and it is easy to cause experimental errors

Abstract

The invention relates to a microscopic microsyringe for chromatography. The microscopic microsyringe comprises a syringe, a syringe needle and a push rod. The outer surface of the syringe is provided with scales, the syringe needle sleeves the front end of the outer wall of the syringe, the push rod is sleeved by the inner wall of the syringe by a rubber plug, a support is fixedly connected to the outer side of the syringe, the support is provided with sliding chutes and a hollow slide block matching the sliding chutes, a magnifier is inserted in the slide block and is arranged right above the scales, the magnifier is parallel to the axial direction of the syringe, the length of the sliding chutes is larger than length of the scales, and the width of the sliding chutes is larger than that of the scales. The microscopic microsyringe has a simple structure, is convenient and practical and is suitable for popularization application.

Description

technical field [0001] The invention relates to a microscopic microinjector for chromatography. Background technique [0002] Commonly used liquid chromatography or gas chromatography is an important branch of chromatography. Liquid chromatography or gas chromatography is to separate the mixed sample through adsorption and desorption in the chromatographic column, and then enter the detector for detection, so as to realize the detection of the sample. quantitative analysis. When liquid chromatography or gas chromatography is used, the first step is to use a micro-syringe to inject the sample. The micro-syringe is equipped with a scale. Since the volume of the micro-syringe itself is small, the scale value marked on it is smaller. It is difficult to read during use, and it is easy to cause experimental errors. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a micros...
