Gas Chromatography

Introduction of Gas Chromatograph

Gas chromatograph is an instrument that uses chromatographic separation technology and detection technology to perform qualitative and quantitative analysis of complex multi-component mixtures. There are many types of gas chromatographs with different functions, but their basic structures are similar. A gas chromatograph is generally composed of a gas circuit system, a sampling system, a separation system (chromatographic column system), a detection and temperature control system, and a recording system.



Application of Gas Chromatograph

1. Environmental protection: analysis, monitoring and research of trace toxicants in polluted places such as atmospheric water sources.

2. Biochemistry: clinical application, pathological and toxicological research.

3. Food analysis: analysis and research of trace components in microbial beverages.

4. Chinese and Western medicine: analysis of raw material intermediates and finished products.

5. Petroleum processing: analysis and control of petrochemical industry, petroleum geology, oil composition, and ore control research.
