Application of correlation analysis for identification of polychlorinated biphenyls

The analytical process was optimized for the determination of individual PCBs in a commercial mixture, Delor 104, and in soil samples contaminated by PCBs. The optimal analytical conditions for the GC-MS system with a DB-5 capillary column involved a temperature program evaluated in terms of information content I(S) and information flow I(S)lt and an identification procedure based on the correlation analysis of the measured and published relative retention r(12) data.
