What is the principle of gas-liquid chromatography?

Gas chromatography is an instrument that uses chromatographic separation and detection technology to perform qualitative and quantitative analysis of complex multi-component mixtures. It is commonly used to analyze thermally stable organic compounds in soil with boiling points not exceeding 500°C, such as volatile organic compounds, organochlorines, organophosphates, polycyclic aromatic hydrocarbons, phthalates, etc.

Principle of gas chromatography: The mixture is first separated using a chromatographic column, and then a detector is used to sequentially analyze the separated components.

Application areas:

Environmental protection: Analysis, monitoring, and research of trace toxic substances in polluted areas such as the atmosphere and water sources.

Biochemistry: Clinical applications, pathological and toxicological research.

Food fermentation: Analysis and research of trace components in microbial beverages.

Traditional Chinese and Western medicines: Analysis of raw materials, intermediates, and finished products.
