编号：20220727007
*高温度：250°C

名称：总烃柱
规格：2m*1/8，60-80目
型号：HH-NMHC-2
编号：20220727006
*高使用温度：300°C
应用：HJ2017环境空气，固定污染源废气，总烃，甲烷，非甲烷总烃的测定 气相色谱法

.非甲烷总烃(nmhc)通常是指除甲烷以外的所有可挥发的碳氢化合物，大气中的nmhc超过一定浓度，除直接对人体健康有害外，在一定条件下经日光照射还会产生光化学反应，生成臭氧等物质，是雾霾、pm2.5的前导因素，在一定的条件下经日光照射还能产生光化学烟雾，对环境和人类造成危害。因此对环境空气、厂界等区域进行非甲烷总烃的监控和管制非常有必要。

现有的非甲烷总烃的测定方法中，主要采用双阀双阀三柱单检测器或双柱单阀单检测器，分别测定甲烷和总烃的浓度，再以差减法计算非甲烷总烃的含量。

*High temperature: 250°C

Name: Total Hydrocarbon Column
Specifications: 2m*1/8, 60-80 mesh
Model: HH-NMHC-2
Number: 20220727006
*High operating temperature: 300°C
Application: Determination of HJ2017 ambient air, stationary pollution source waste gas, total hydrocarbons, methane, and non-methane total hydrocarbons by gas chromatography

.Non-methane total hydrocarbons (nmhc) usually refer to all volatile hydrocarbons except methane. The nmhc in the atmosphere exceeds a certain concentration, which is not only directly harmful to human health, but also produces photochemical reactions under certain conditions. The reaction produces ozone and other substances, which are the leading factors of haze and pm2.5. Under certain conditions, sunlight exposure can also produce photochemical smog, causing harm to the environment and humans. Therefore, it is very necessary to monitor and control non-methane total hydrocarbons in areas such as ambient air and plant boundaries.

In the existing method for measuring non-methane total hydrocarbons, a double-valve double-valve three-column single detector or a double-column single-valve single detector is mainly used to measure the concentrations of methane and total hydrocarbons respectively, and then calculate the non-methane total hydrocarbons by subtraction method. content.
