| 摘 要： | 依据HJ/T 400-2007《车内挥发性有机物和醛酮类物质采样测定方法》,采用液相色谱法对车内空气中醛类物质进行定量分析,对测试过程中可能影响不确定度的因素进行全面分析和评定,得出控制不确定度的关键因素在于控制好操作重复性、采样泵流量准确性、溶液配制引入的不确定度。

| Abstract: | According to HJ/T 400—2007,quantitative analysis to aldehydes of air in cabin interiors was carried out by using liquid chromatography,and the factors that may affect the uncertainty in the test process were analyzed and evaluated.It is concluded that the key factors to control the uncertainty are to control the operational repeatability,flow accuracy of the sampling pump,solution preparation and linear fitting. |
