Adsorption tube for non-methane total hydrocarbons
Adsorption tube for non-methane total hydrocarbons Details:

Stationary phase: mixed

Granularity: 60-80 mesh

Specification: HH-NMHC1754, other specifications can be customized

Material: glass, stainless steel

Shape: straight type, U type

Application: Enrichment of non-methane total hydrocarbons in ambient air/stationary pollution source exhaust gas

The ratio of the measured value to the theoretical concentration of ethylene (olefin), toluene (aromatic hydrocarbon), ethyl acetate (oxygen derivative), trichloroethylene (halogenated hydrocarbon) and n-undecane (alkane) should be within a certain range ：Ethylene≥60%, toluene 90%~105%, ethyl acetate≥60%,

Trichloroethylene 95%~110%, n-undecane ≥60%.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. provides a simple method for the analysis and determination of ultra-trace non-methane total hydrocarbons in the atmosphere: adsorbent enrichment, sampling at a flow rate of 0.5-1L/min for several hours to 24h, using FID -GC method, can easily detect the total non-methane hydrocarbons in the atmosphere, the minimum detection concentration can reach 10ppt, the method is simple and reliable, and is suitable for routine monitoring.
