HH-NMHC-1 环境大气中非甲烷总烃单柱直测专用柱

名称：甲烷总烃柱
规格：1m*1/8

型号：HH-NMHC-1

应用：非甲烷总烃直测法2021标准

随着我国石油工业的飞速发展及汽车数量的日益增多,大气中烃类的污染较为严重,它与氮氧化物在阳光紫外线照射下产生“光化学烟雾”.经国外长期研究证明,烃类是形成“光化学烟雾”的重要起源物质.为此,要研究“光化学烟雾”的污染规律,首先弄清楚烃类在大气中的污染状况是十分必要的.

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.

Special column for single-column direct measurement of non-methane total hydrocarbons in ambient atmosphere
Special column for single-column direct measurement of non-methane total hydrocarbons in ambient atmosphere Details:
Name: methane total hydrocarbon column
Specifications: 1m*1/8

Model: HH-NMHC-1

Application: 2021 Standard for Direct Measurement of Non-Methane Total Hydrocarbons

With the rapid development of my country's petroleum industry and the increasing number of automobiles, the pollution of hydrocarbons in the atmosphere is more serious, and it and nitrogen oxides produce "photochemical smog" under sunlight and ultraviolet radiation. An important source of "photochemical smog". To study the pollution law of "photochemical smog", it is necessary to first clarify the pollution status of hydrocarbons in the atmosphere.

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, rapid and accurate.
