      • Product Overview
      • MessageEmail

        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.

        • Features

        • Use enrichment device to reduce detection limit of gas chromatograph

          Analysis gas path is equipped with auto purge, reducing residue of sample, improving accuracy and avoiding cross contamination

          Compact structure, convenient for use and maintenance, high reliability

          Explosion-isolation cabinet is optional, applied to explosion-proof occasions

        • Applications

        •         Applied in trace VOCs monitoring in the atmospheric environment and factory boundary environment

        • Specifications
