Zetian - Model GCOM-3000 -Trace VOCs Online Monitoring System

SHARE

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.
