浩瀚色谱(山东)应用技术开发有限公司,采用十通阀进样,13X甲烷柱和硅烷化玻璃微珠总烃柱分离、单FID检测器气相色谱法,一次进样可测得环境空气或固定源中的甲烷、总烃及非甲烷总烃的检测数据.不同氧气含量的气体样品在分析过程中,氧气峰对总烃的干扰情况,指出避免单独检测除烃气样的可行性.实验采用注射器采样,样品最佳的放置时长在7.8h之内.方法的检出限为:总烃与非甲烷总烃均为0.05mg/m3;重复性相对标准偏差低于1.6%;方法的加标回收率分别是总烃在92.3%~ 112.0%之间,非甲烷总烃在91.8%~110.5%之间.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts a ten way valve injection, 13X methane column and silane glass bead total hydrocarbon column separation, and single FID detector gas chromatography method. One injection can measure the detection data of methane, total hydrocarbons, and non methane total hydrocarbons in ambient air or fixed sources The interference of oxygen peaks on total hydrocarbons during the analysis of gas samples with different oxygen contents is discussed, and the feasibility of avoiding separate detection of hydrocarbon removal gas samples is pointed out The experiment used a syringe for sampling, and the optimal placement time for the sample was within 7.8 hours The detection limit of the method is: both total hydrocarbons and non methane total hydrocarbons are 0.05 mg/m3; The relative standard deviation of repeatability is less than 1.6%; The spiked recovery rates of the methods are between 92.3% and 112.0% for total hydrocarbons and between 91.8% and 110.5% for non methane total hydrocarbons
