Hangzhou Chunlai Technology CO., Ltd. products

The GCOM-3000 (A2) adopts low-temperature cold trap adsorption-thermal desorption technology combined with hydrogen flame ionization detection technology to concentrate non-total methane hydrocarbons in the sample gas and reduce the detection limit of the gas chromatography analyzer through the direct measurement method with Tenax-based segmented combination adsorbent tubes, together with MFC electronic flow control. The analyzer`s internal analytical gas path adopts whole-process heat tracing without cold point design, which effectively reduces the adsorption of trace high-boiling point NMHC sample components, and it is suitable for on-line continuous automatic monitoring of NMHCs in ambient air and perimeter air of industrial parks.

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.

GCOM-3010 Ambient Air NMHC Online Analyzer (Gas Chromatograph) has increased an automatic sampling module based on GCOM-3000 Stationary Pollution Source NMHC Online Analyzer. The core module of the analyzer adopts specialized chromatographic column combination, gas path purge technology and Flame Ionization Detector (FID) technology which is suitable for continuous and automatic online monitoring of non-methane total hydrocarbons in atmospheric air and the air around industrial parks.
