在石油化工生產(chǎn)中產(chǎn)生的大量C_1～C_9烷烴和烯烴的混合物,統(tǒng)稱為總烴。烴類易燃易爆,且污染環(huán)境和危害人體健康。目前車間空氣監(jiān)測中尚未有測定總烴的方法。
滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，研究了用活性炭管富集空氣中C_2～C_9烴類,熱解吸后進(jìn)行色譜分析的方法。各種烴類氣體不需要分離直接進(jìn)入氫火焰檢測器,得一個總色譜峰。該法準(zhǔn)確、快速、簡易可行。

A large amount of a mixture of C_1 to C_9 alkanes and olefins produced in petrochemical production is collectively referred to as total hydrocarbons. Hydrocarbons are flammable and explosive, pollute the environment and endanger human health. There is currently no method for determining total hydrocarbons in the air monitoring of the workshop.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. studied the method of enriching C_2～C_9 hydrocarbons in air with activated carbon tubes and performing thermal desorption for chromatographic analysis. A variety of hydrocarbon gases do not need to be separated directly into the hydrogen flame detector to give a total peak. The method is accurate, fast, and simple.
