The ambient air is collected by the sampling system and then enters the concentration system. Under ultra-low temperature conditions, volatile organic compounds in the atmosphere are frozen and captured in an empty capillary column; then the compounds are quickly heated and analyzed to make the compounds enter the GCMS analysis system; after being separated by chromatographic column, they are detected by FID and MS detector.
The capture efficiency and desorption efficiency of the system are higher than that of the adsorbent. The detection limit of the system is low and the repeatability is good;
The unique two-way capture and two-way analysis technology allows two detectors to analyze at the same time to improve the data integrity and chromatographic resolution;
GC-MS can be used for qualitative and quantitative analysis of known compounds and unknown compounds, which overcomes the disadvantages of FID detector that can only analyze known compounds, but can not qualitatively analyze unknown compounds;
It has excellent ability to capture and analyze volatile organic compounds (such as ethane and ethylene) with low boiling point.
It can be used for industrial hygiene and full analysis of toxic and harmful gases at work site
It can be used for urban air quality monitoring, VOCs qualitative and quantitative analysis in key monitoring areas and plant boundaries
It can be used for the third party inspection and testing institutions
It can be used for emergency monitoring in case of sudden environmental pollution events (mobile)
