Development in the Analysis of Chlorobiphenyls in Environmental Matrices for Certification Purposes

Abstract
The development of methods for the determination of chlorobiphenyls in environmental matrices for the certification of Reference Materials has recently concentrated on improving chromatographic separation techniques, chemical ionization-negative ion mass spectrometry, and the control of calibration procedures. The information has been disseminated through a BCR workshop, and the open literature. An overview of the progress made is given.
