Determination of non-methane hydrocarbons in the atmosphere
Determination of non-methane hydrocarbons in the atmosphere Methane column Details:

Stationary phase: polymer pellet
GDX-502, 2m*3mm, 2m*4mm, 2m*1/8, 60-80 mesh
Methane column

Total hydrocarbon column
2m*3mm, 2m*4mm, 2m*1/8, silanized glass microspheres

The results of recent research on sampling methods, concentration determination and component analysis of non-methane hydrocarbons in the atmosphere are reviewed. A series of non-methane hydrocarbon automatic determination methods were compared, and the methods of non-methane hydrocarbon enrichment and concentration, desorption injection and analysis techniques and research progress at home and abroad were elaborated.

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd., through experiments, replace the hydrocarbon removal air unit with a hydrocarbon removal air cylinder, and determine the total hydrocarbon and methane hydrocarbon content in the air by gas chromatography. The difference between the two is non-A. The method of the content of alkanes was used to determine the content of non-methane hydrocarbons in the atmosphere, and satisfactory results were obtained in the experiment.
