The GC6010 volatile organic compound non methane total hydrocarbon online monitoring system adopts the principle of gas chromatography hydrogen flame ionization detector (GC-FID). After entering the analyzer, the sample is collected into the quantitative loop, and the sample in the quantitative loop is sent to the chromatographic column for separation through a carrier gas. The separated components then enter the FID detector for detection. During sample analysis, the total hydrocarbon content is obtained by entering the FID detector through an empty column; The other way is separated by a chromatographic column, where methane first passes through the column and enters the detector to obtain its content. Then, the non methane total hydrocarbons still remaining in the pre column are blown back through valve switching. Using the difference method, subtract the CH4 (methane) concentration from the measured THC (total hydrocarbons) concentration to obtain the concentration of NMHC (non methane total hydrocarbons). This system adopts a five position ten way valve, combined with the patented chromatographic blowback method, resulting in accurate and reliable results.
Analysis method: Gas chromatography
Typical applicationsNon methane total hydrocarbons, benzene derivatives, etc
