Determination of non-methane total hydrocarbons in ambient air by HH-NMHC-2 silanized glass microspheres
Determination of non-methane total hydrocarbons in ambient air by HH-NMHC-2 silanized glass microspheres Details:

Name: total hydrocarbon column Total hydrocarbon determination column, made of stainless steel or hard glass, 2 m long, 4 mm inner diameter, filled with 60-80 mesh silanized glass beads, or other equivalent packed columns.

2m*1/8

Application: Determination of methane, total hydrocarbons and non-methane total hydrocarbons in HJ2017 ambient air/stationary pollution source waste gas

Applies to: Agilent, Thermo Fisher, Varian, Bruker, PE


In order to master the technical ability of laboratory detection of non-methane total hydrocarbons, in 2021, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. will participate in the assessment of non-methane total hydrocarbons in ambient air of the National Environmental Monitoring Station. Determination of Methane and Non-Methane Total Hydrocarbons by Direct Injection-Gas Chromatography" (HJ 604-2017), the ability assessment results are satisfactory. The results show that the direct injection-gas chromatography with double-valve double-column double-hydrogen flame ionization detector can simultaneously measure total hydrocarbons, methane and non-methane total hydrocarbons in ambient air with high accuracy, precision and repeatability. It has good performance, short analysis time, and the correlation coefficients of the calibration curves of total hydrocarbons and methane are all greater than 0.999. This method is suitable for the daily detection of non-methane total hydrocarbons in ambient air.
