Zetian - Model GCOM-3000 (A2)-BTEX -VOC Analyzer
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.
