固定污染源废气总烃甲烷和非甲烷总烃的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》。

固定污染源废气总烃甲烷和非甲烷总烃的测定脱活毛细管空柱

色谱（）应用技术开发用气相色谱仪配双氢火焰检测器，双毛细管柱柱分析固定污染源排气中总烃，甲烷，氧峰从而得到非甲烷总烃(NMHC)含量.当色谱进样量为1.0mL时，方法的检出浓为410-2mg/m3，方法的定量检定浓范围为0.12～32mg/m3.着重介绍独特的标准气体的配制方法及进样方法，保证了非甲烷总烃(NMHC)测试的准确性.
