Portable methane/non methane total hydrocarbon gas chromatograph

Method Principle

Sample ImportNmhf- 60Portable methane/After the non methane total hydrocarbon gas chromatograph, it is quantitatively injected into both the total hydrocarbon detection unit and the methane detection unit (separated by a chromatographic column and entering)FIDMeasure the content of total hydrocarbons and methane separately, and the difference between the two is the content of non methane total hydrocarbons.

Standard Configuration

Instrument host (including automatic injection control moduleFIDDetector module, sample separation moduleEPCGas path control module, gas source module, circuit control module, power module), sampling pipeline (including heat tracing pipeline, sampling probe, filtering device), tablet computer.
