Calibrants and Calibration for Chlorobiphenyl Analysis

Abstract

Abstract Guidelines are given for the preparation of calibration solutions and the calibration of the capillary gas chromatograph for the determination of chlorobiphenyls (CBs) and ways in which errors may be reduced to produce comparable data in the analysis of environmental samples. Results from a Community Bureau of Reference (BCR) intercomparison exercise indicate that calibration remains a key factor in obtaining reliable data.
