大气和废气中非甲烷总烃测定脱活毛细管空柱

产品详情

非甲烷总烃(NMHC)指除甲烷以外挥发性碳氢化合物(其中主要是C2C8)的总合，长期以来一直是环境空气监测的一项重要指标，我国《大气污染物综合排放标准》GB规定非甲烷总烃的厂界浓标准为4mgm-3，《固定污染源排气中非甲烷总烃的测定气相色谱法》。

大气和废气中非甲烷总烃测定脱活毛细管空柱

色谱（）应用技术开发采用十通阀、双定量环进样，双色谱柱分别分离两路气样，单FID检测器检测的方法测定固定污染源废气中的总烃、甲烷和非甲烷总烃.样品分析一次进样同时获得总烃和甲烷的数据，避免进样误差，大大节省了分析时间，具有操作简单、方法快速、重现性好等特点.
