名称：甲烷总烃复合柱
规格：1m*1/8
型号：HH-NMHC-1
应用：环境空气非甲烷总烃连续自动监测技术规定（试行）2021

浩瀚色谱（山东）应用技术开发有限公司采用单柱单氢火焰离子检测器（FID）气相色谱法测定空气中的非甲烷总烃（NMHC）和甲烷,通过十通阀进样和切换,实现一次进样就可以完成甲烷和NMHC的同步测定,且无氧峰干扰。与双柱双FID检测器气相色谱法相比,该方法不用测算氧峰,更加简便,分析结果准确,且重复性良好。

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.
