Determination of Non-Methane Total Hydrocarbons (NMHC) in Exhaust from Stationary Pollution Sources
Determination of non-methane total hydrocarbons (NMHC) in stationary pollution source exhaust gas Details:

Name: Total Hydrocarbon Column
Material: Passivated
Specifications: 50cm*1/8
Model: HH-THC-0.5
Application: Ambient air, stationary pollution source waste gas Determination of non-methane total hydrocarbons

Taking energy as a clue, the NMHC emissions from various anthropogenic sources in the atmosphere were classified and quantitatively determined by means of gas chromatography-mass spectrometry-computer. On this basis, the emission characteristics of NMHC from petrochemical, transportation, coal-fired and residential LPG and their contribution to atmospheric NMHC are analyzed. The results show that transportation and petrochemicals are the anthropogenic sources that contribute the most to atmospheric NMHC, followed by coal-fired industries. The characteristic species of NMHC in the atmosphere have also been tentatively studied.

Strengthening the monitoring of NMHC in stationary pollution sources is beneficial to human health, environmental safety and ecological balance, and the detection of NMHC content by gas chromatography with double-column double-hydrogen flame ionization is better.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. improved HJ/T38-1999 "Gas Chromatography Method for Determination of Non-Methane Total Hydrocarbons in Exhaust from Stationary Pollution Sources". The detection of non-methane total hydrocarbons (NMHC) of organized and fugitive emissions can be put into use. The detection amount of NMHC was 4×10-2ng. When the chromatographic injection volume was 1.0 mL, the detection concentration of the method was 0.278 2 mg/m3, and the quantitative determination concentration range of the method was 0.12~32 mg/m3.

The HH-THC-0.5 total hydrocarbon column developed by Haohan Chromatography has high column efficiency, symmetrical peak shape, no bifurcation, and only one chromatographic peak. A vast spectrum of unique products.
