Description

Technical Field

[0001] This utility model relates to the field of instrument protection technology, specifically a gas chromatograph protection mechanism. Background Technology

[0002] A gas chromatograph (GC) is an instrument that uses chromatographic separation and detection techniques to perform qualitative and quantitative analysis of complex mixtures of multiple components. It is typically used to analyze thermally stable organic compounds in soil with boiling points not exceeding 500°C, such as volatile organic compounds, organochlorines, organophosphorus compounds, polycyclic aromatic hydrocarbons, and phthalates. While there are many types of GCs with varying functions, their basic structure is similar. A typical GC consists of a gas path system, an injection system, a separation system (chromatographic column system), a detection and temperature control system, and a recording system.

[0003] Gas chromatographs are high-precision instruments. During transportation, they are subject to bumps and jostles. Using a special box to hold the instrument can reduce the risk of impact. However, the instrument is large, and the box is also large. The box takes up a lot of space outside of transportation and is not easy to store. Utility Model Content
