Portable non-methane total hydrocarbon gas chromatograph
Portable non-methane total hydrocarbon gas chromatograph Details:

The GC-7990F portable non-methane total hydrocarbon gas chromatograph adopts the hydrogen flame detector FID, which can measure the total hydrocarbon and methane in the ambient air and fixed pollution source exhaust gas. It can automatically and continuously sample, continuously monitor, and has a fast response speed. The sampling system and the analysis system are kept in a controlled high temperature state throughout the process, effectively preventing sample condensation or loss, and realizing the monitoring of total hydrocarbons/methane/non-methane total hydrocarbons.

in accordance with:
GB/T 16157-1996 Determination of particulate matter in exhaust gas from stationary sources and sampling method for gaseous pollutants
HJ 1012-2018 Ambient air and exhaust gas total hydrocarbon, methane and non-methane total hydrocarbon portable monitor technical requirements and testing methods
DB 11/T 1367 Determination of fixed source exhaust gas methane/total hydrocarbons/non-methane total hydrocarbons portable hydrogen flame ionization detector method


After the sample is imported into the portable non-methane total hydrocarbon analyzer, it should be able to be quantitatively injected into the total hydrocarbon detection unit (FID) and the methane detection unit at the same time (the methane detection unit can oxidize all other organic compounds except methane into carbon dioxide and water through a catalyst. FID detects methane), and simultaneously determines the content of total hydrocarbons and methane. The difference between the two is the content of non-methane total hydrocarbons.

1. Highly integrated design, portable and convenient
2. Easy to use and simple to operate
3. High automation program, powerful software
4. The measurement is accurate and guaranteed
5. Comprehensive quality control function
