标准摘要
[中文适用范围]： 本部分ISO 16000规定了从室内空气中收集在聚四氟乙烯泡沫（PUF）背衬的颗粒过滤器上的多氯联苯（PCBs）、多氯二苯并-p-二噁英（PCDDs）和多氯二苯并呋喃（PCDFs）的提取、净化和分析程序。该方法结合了高分辨气相色谱与高分辨质谱（HRGC/HRMS）进行特定分析。该方法可为四氯至十氯联苯和四氯至八氯二苯并-p-二噁英/二苯并呋喃（每种同系物系列的总浓度）提供准确的定量数据。该方法能够检测出0.2 pg/m³或更低浓度的大多数PCBs和PCDFs/PCDDs，空气采样体积可达360 m³或更多（特殊情况下）。然而，在较低的采样体积下，可能无法检测到所有分析物。在正常条件下，精密度预计为±25%或更好，不确定度为±50%或更好。 [外文原描述]： ISO 16000-14:2009 specifies extraction, clean-up, and analysis procedures for the determination of polychlorinated biphenyls (PCBs), polychlorinated dibenzo- p -dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) collected from indoor air on particle filters backed by polyurethane foam (PUF). The method incorporates specific analyses by high resolution gas chromatography combined with high resolution mass spectrometry (HRGC/HRMS). The method provides accurate quantitative data for tetra- to decachlorobiphenyls and tetra- to octachloro-dibenzo- p -dioxins/dibenzofurans (total concentrations for each isomeric series). It is capable of detecting 0,2 pg/m 3 or lower concentrations of most PCBs and PCDFs/PCDDs with air sampling volumes up to 360 m 3 or more in special cases. However, it may not be possible to detect all analytes at 0,2 pg/m 3 or lower, especially at lower sampling volumes. Precision under normal conditions can be expected to be ±25 % or better and uncertainty ±50 % or better.
