大气TSP采样滤膜上PAHs分布的均匀性研究

Study of Distribution of Polycyclic Aromatic Hydrocarbons on Total Air Suspended Particulates Sampling Filter

标准参考物质（ＳＲＭ）是分析方法研究的基础，也是质量保证较为可信的手段。本文通过对大气ＴＳＰ采样滤膜上ＰＡＨｓ分布的均匀性研究，发现ＰＡＨｓ在滤膜上是均匀分布的。由此，我们提出了滤膜四等分法和八等分法，以获得可用于分析方法研究的实验用参考物质。

Standard reference matter(SRM)is the basis of analytical method studying,and is reliable method of quality assurance as well.By studying distribution of polycyclic aromatic hydrocarbons(PAHs) on total air suspended particulates sampling filter,we found that the PAHs were well distributed on the filter.Thus,we developed the four equal parts of filter method and the eight equal parts of filter method to obtain laboratory-use reference matter of studying of analytical method.
