摘要
用气相色谱仪配双氢火焰检测器、双不锈钢填充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1.0 mL时,方法的检出浓度为4×10-2mg/m3,方法的定量检定浓度范围为0.12～32 mg/m3。文章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。
Using a gas chromatograph equipped with a hydrogen flame detector,and double stainless steel packed column total hydrocarbon,methan,and oxygen peak of stationnary source emission were analyzed,resulting in non methane hydrocarbon（NMHC） content.When the chromatography sample volume of 1.0 ml,the detection concentration was 4×10-2 mg/m3,and a the quantitative assay concentration was 0.12~32 mg/m3.The unique standard gas preparation method and injection method were mainly introduced to ensure the accuracy of testing NMHC.
