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.目前分析总烃的手段并不多,有选择燃烧法,红外法,色谱法等.色谱法对分析烃类具有灵敏度高,速度快等优点,大多数都采用以CH_4为标气,测得总烃浓度以。

Gas chromatographic determination of total hydrocarbons, methane and non-methane hydrocarbons in the atmosphere
Gas chromatographic determination of total hydrocarbons, methane and non-methane hydrocarbons in the atmosphere Details:

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. It and nitrogen oxides produce "photochemical smog" under the irradiation of sunlight and ultraviolet rays. Long-term foreign studies have proved that hydrocarbons are the 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. At present, there are not many methods for analyzing total hydrocarbons, and there are options. Combustion, infrared, chromatography, etc. Chromatography has the advantages of high sensitivity and fast speed for analyzing hydrocarbons. Most of them use CH_4 as the standard gas to measure the total hydrocarbon concentration.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used double-column double-hydrogen flame ionization detector gas chromatography to analyze non-methane hydrocarbons in gas samples. The detection limit of the method is 0.035mg/m3, and the determination range is 0.12～8.0mg/ The verification experiment results of m3.5 laboratories show that the relative standard deviation is 3.4%～9.2%, and the recovery rate is 88.6%～114%
