DW-GC1120 Gas Chromatography

Gas Chromatography is a kind of instrument for qualitative and quantitative analysis of multicomponent complex mixture by using chromatographic separation technology and detection technology. Generally, it can be used to analyze the thermal stable organic compounds in soil, such as volatile organic compounds, organic chlorine, organic phosphorus, polycyclic aromatic hydrocarbons, phthalates, etc.
