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.
