Overview Of GCOM-3000 Trace VOCs Online Monitoring System
GCOM-3000 trace VOCs Online Monitoring System, composed by sampling pretreatment system, enrichment concentration system, chromatographic analysis system and data transmission system, can monitor gaseous organic pollutants including non-methane hydrocarbon, benzene series(benzene, methylbenzene, xylene,etc) in the air. Measured gas enters high-temperature chromatographic analysis module(GC-FID) after water removal, filtering, low-temperature enrichment and high-temperature analysis. Enrichment device can concentrate trace amount of volatile organic compounds and reduce the detection limit of gas chromatograph.
