摘要
对固相吸附-高效液相色谱法测定乘用车内空气中的醛酮类有机物结果进行不确定度评定,得汽车车内空气中醛酮类有机物测定值的扩展不确定度分别为:甲醛0.0013 mg/m3、乙醛0.00076 mg/m3、丙烯醛0.00098 mg/m3。对各不确定度分量进行分析比较,发现采样过程中的采样体积及分析过程中的标准溶液配制的不确定度分量最大,建议在进行车内空气质量检测工作中应着重对这两个分量进行控制。
The uncertainty of determination results of aldehydes and ketones in air inside car by HPLC with solid phase adsorption was evaluated.The expanded uncertainties were 0.0013 mg/m3 for formaldehyde,0.00076 mg/m3 for acetaldehyde,and 0.00098 mg/m3 for acrolein.The uncertainty components were analysized,and it was found that the main impacts on uncertainty were the volume in the sampling process and the preparation of standard solution in the analysis procedure which should be paid special attention to.
