A collaborative study of 209 PCB congeners and 6 Aroclors on 20 different HRGC columns .1. Retention and coelution database

The elution orders and predicted coelutions of all 209 PCB congeners were obtained for 27 HRGC-ECD or HRGC-MS systems comprising 20 different stationary phases. The resultant database facilitates selection of the columns most suitable for developing particular comprehensive, quantitative, congener-specific PCB analyses, the design of the minimum number of congener mixtures needed to calibrate such analyses, and the testing of retention prediction algorithms based on structure relationships of GC phases and congener substitution patterns.
