直接测定空气中甲烷和非甲烷总烃
直接测定空气中甲烷和非甲烷总烃 详细信息：

浩瀚色谱（山东）应用技术开发有限公司采用柱切换反吹气相色谱法测定环境空气中的甲烷和非甲烷总烃。通过十通阀切换使甲烷与所有非甲烷烃类化合物彻底分离开来,一次进样可直接测定甲烷和非甲烷总烃。该方法可消除双离子化检测器因灵敏度的差异性引起的误差。方法简单、快速,分析结果准确。

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

Direct determination of methane and non-methane total hydrocarbons in air
Direct determination of methane and non-methane total hydrocarbons in air Details:

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses column-switched backflush gas chromatography to determine methane and non-methane total hydrocarbons in ambient air. Methane and all non-methane hydrocarbon compounds can be completely separated by switching the ten-way valve, and methane and non-methane total hydrocarbons can be directly determined by one injection. This method can eliminate the error caused by the difference in sensitivity of the double ionization detector. The method is simple, rapid and accurate.

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
