Determination of non-methane total hydrocarbons in ambient air GDX-502
Determination of non-methane total hydrocarbons in ambient air GDX-502 Details:

In order to master the technical ability of laboratory detection of non-methane total hydrocarbons, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., in accordance with "Determination of ambient air total hydrocarbons, methane and non-methane total hydrocarbons by direct injection-gas chromatography" (HJ 604— 2017), and the results of the ability assessment were 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.
