Special column for direct injection determination of non-methane total hydrocarbons in ambient air
Special column for direct injection determination of non-methane total hydrocarbons in ambient air Details:

Name: Methane total hydrocarbon composite column
Specifications: 1m*1/8
Model: HH-NMHC-1
Application: Technical Regulations for Continuous Automatic Monitoring of Non-methane Total Hydrocarbons in Ambient Air (Trial) 2021

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a single-column single-hydrogen flame ionization detector (FID) gas chromatography to determine non-methane total hydrocarbons (NMHC) and methane in air. Through the ten-port valve injection and switching, one-time Simultaneous determination of methane and NMHC can be accomplished by injecting the sample without the interference of oxygen peaks. Compared with the dual-column dual-FID detector gas chromatography method, this method does not need to measure the oxygen peak, which is simpler, and the analytical results are accurate and reliable, and the repeatability is good.
