Gas chromatograph is an instrument for qualitative and quantitative analysis of complex mixtures of multi-components using chromatographic separation technology and detection technology,. It can usually be used to analyze organic matter in soil that is thermally stable and has a boiling point not exceeding 500°C, such as volatile organic compounds, organochlorine, organophosphorus, polycyclic aromatic hydrocarbons, phthalate esters, and so on.
