SENSHANG INSTRUMENT

First, System introduction SS-700 flue gas VOCs monitoring system is based on Hj/t80, Hj/t75, hj/t76 and other related standards, using extraction method sampling, configuration based on advanced gas chromatography, mass spectrometry and other separation technology and hydrogen flame ionization detector (FID), Optical ionization detector (PID) and other detection methods, the components of volatile organic gases such as total hydrocarbon (THC), non-methane total hydrocarbons (NMHC), aromatic hydrocarbons and esters in the exhaust gas are measured according to the composition and testing requirements of each sample in the analysis project, which can meet the requirements and analysis frequency of the analysis project.
At the same time, the optimization of the instrument configuration can maximize the utilization rate of the instrument and ensure the continuity and reliability of the sample analysis work.
The analysis system fully considers the sample gas condition and dew point, and designs the pretreatment system to prevent the crystallization condensation and the component concentration change of the sample gas. The instrument adopts special chromatographic column combination, Central cutting plus back blowing technology and hydrogen flame ionization detector (FID) technology to detect.

FID hydrogen Flame ionization detector is a typical quality detector, which measures the mass change velocity of a component in gas chromatographic carrier gas, and the response value is proportional to the quality of a component entering the detector in the unit time.
