[0002] Gas chromatograph is an instrument that uses chromatographic separation technology and detection technology to perform qualitative and quantitative analysis on complex mixtures of multiple components. There are many types of gas chromatographs with different functions, but their basic structures are similar. Gas chromatography is a chromatographic analysis method using gas as the mobile phase, mainly used to separate and analyze volatile substances. Gas chromatographs are widely used in the fields of medicine and health, petrochemicals, environmental monitoring, biochemistry, etc. Since some gas chromatographs are relatively heavy, they will be installed on a mounting base for use.

Moreover, after a period of use, the bolts may become loose due to vibration, affecting the normal operation and use effect of the chromatograph, and failing to meet the use requirements. In view of this, we propose a gas chromatograph that is easy to install. Utility Model Content
