Direct Determination of Non-Methane Total Hydrocarbons in Ambient Air Methane Composite Column HH-NMHC-1
Direct Determination of Non-Methane Total Hydrocarbons in Ambient Air Methane Composite Column HH-NMHC-1 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 column-switched backflushing gas chromatography to determine methane and non-methane total hydrocarbons in ambient air. The ten-way valve switching enables methane and all non-methane hydrocarbon compounds to be completely separated. The sample injection can directly measure methane and non-methane total hydrocarbons. This method can eliminate the error caused by the sensitivity difference of the double ionization detector. The method is simple, fast, and the analysis results are accurate.
