Zetian - Model GCOM-4000-VOCs -Water Volatile Organic Compounds Online Analyzer

GCOM-4000-VOCs is composed by headspace sample introduction module and high temperature chromatographic analysis module (GC-FID). It is able to monitor benzene series (benzene, toluene, xylene, ethylbenzene, styrene, etc.) and other volatile organic pollutants in industrial wastewater and surface water section. The water sample is pumped into headspace pool of analyzer through pretreatment pipeline; under condition of constant temperature heating, the volatile organic compounds in water sample are transferred to gas phase space above the liquid surface, then the volatile sample gas is transferred to high temperature chromatographic analysis module for detection through pressurizing and decompressing of carrier gas. Through the process of changing liquid phase to gas phase via headspace sampling device, volatilized clean gas can be measured directly. The influence of impurities (such as suspended matter) in water on the analysis flow path can be overcome.
