haohan测定环境空气及废气中的非甲烷总烃GDX-502+玻璃微球柱

Total hydrocarbons and total non-methane hydrocarbons Measurement method: the use of six-way valve to the quantitative determination of ambient air and exhaust gas concentrations of non-methane hydrocarbon ring sampling, analysis Xiangying Tengzhou City Technology Co., Ltd. developed the GDX-502 column packed with Glass Microspheres ball packed column, instrument conditions were optimized, the detection limit was 0.13 mg / m ^ 3, the total hydrocarbon standard sample relative standard deviation of 0.4% relative standard deviation of 1.2% methane, total hydrocarbon recoveries of 100.9-101.6% methane recovery was 102.4-102.6%, the method is simple, rapid analysis, test results were satisfactory.

总烃和非甲烷总烃测定方法：利用六通阀定量环进样来测定环境空气以及废气中的非甲烷总烃浓度,浩瀚色谱（山东）应用技术开发有限公司研发出GDX-502填充柱+玻璃微球填充柱，对仪器条件进行优化,方法的检出限为0.13 mg/m^3,标样总烃相对标准偏差为0.4%,甲烷的相对标准偏差为1.2%,总烃的加标回收率为100.9-101.6%,甲烷的加标回收率为102.4-102.6%,该方法操作简单,分析速度快,实验结果满意。
