Abstract

The analysis of polychlorinated biphenyls (PCBs) in a wide variety of environmental samples is discussed, starting with the more traditional methodology and moving on to more recent developments that are expected to continue in the twenty-first century. Several detection techniques, including gas chromatography (GC) coupled with electron capture detection (ECD) and mass spectrometry (MS), are described in the first part of this article. The use of MS as a detection technique is discussed in detail, from both a qualitative and a quantitative point of view. To a large extent the detection technique used determines the sample pretreatment and clean-up, and in later paragraphs column clean-up on adsorbents is discussed, including fat removal, alumina column chromatography and planar separation on carbon. A new methodology for the analysis of PCBs in environmental samples is also described. Both speed of analysis using gas chromatography/time-of-flight mass spectrometry (GC/TOFMS) and environmentally friendly analysis using supercritical CO2 are discussed in detail. In the last section several aspects of quality assurance/quality control (QA/QC) are discussed using an international intercalibration study as an example.
