This document specifies sampling from stationary sources, extraction, clean-up, identification and quantification procedures of the dioxin-like PCBs. The procedure described lays down requirements to measure the PCB congeners given in Annex A (see Table A.1). It is applicable to the twelve non- and monoortho PCB designated by the WHO. It is optimised to measure PCB concentrations in the range of 0,01 ng WHO-TEQ/m. In addition to the 12 non- and mono-ortho-PCB the present document is also applicable to measure further PCB-congeners like the so-called “marker PCB” 28, 52, 101, 138, 153, 180 (see Annex D). This document specifies a framework of quality control requirements which have to be fulfilled by any PCB sampling, extraction, clean-up, identification and quantification methods to be applied. It is assumed that due to their similar chemical behaviour PCBs may be sampled from stationary sources together with the PCDDs/PCDFs by the same methods. The complete sampling procedure is described in the EN 1948-1. Each of the three sampling methods of EN 1948-1 can be combined with the methods described in this document to complete the measurement procedure. EN 1948-1 is an integral part of the complete measurement procedure and is necessary for the determination of PCBs. In addition it is possible to measure PCBs together with PCDDs/PCDFs by applying EN 1948 Part 1, Part 2, Part 3 and CEN/TS 1948 Part 4.
