摘要
测定计算了便携式红外光谱仪分析几种气体污染物时的检出限,结果显示一氧化碳检出限低于1mg/m^3,也低于《环境空气质量标准》(GB3095-2012)和《室内空气质量标准》(GBT18883-2002)中相应标准限值;四氯化碳、二氧化硫和一氧化氮检出限界于1mg/m^3和10mg/m^3之间,苯、甲苯、丙酮检出限大于10mg/m3。
This article determined the detection limit of several kinds of atmosphere pollutants measured by portable emergency monitoring infrared spectrometer. The results show that the detection limit of CO is less than 1 mg/m^3,which is under the corresponding standards: GB3095-2012 and GBT18883-2002. The detection limit of CCl_4,SO_2,NO is between 1 mg/m^3 to10 mg/m^3. The detection limit of C_6H_6,C_6H_5CH_3,CH_3COCH_3 is over 10 mg/m^3.
