Through the use of two capillary GC columns: 40% octadecyl/ 15% phenyl methyl siloxane and 50% phenyl methyl siloxane, it was possible to separate 201 PCB congeners with only four unresolved pairs. The data compiled in this study for all 209 congeners will aid in the identification of selected individual components of these environmental pollutants. The use of this data also presents the opportunity for the improved quantification of the commercial PCB formulations. -from Authors
Synthesis of C 14 labeled environment contaminants

Upon the reaction of benzene-14C via nitrobenzene-14C and aniline-14C, some 14C-labelled environmental contaminants were were synthesized. By chlorination of aniline-14C and acetanilide-14C the authors prepared chloroanilines-14C. Gomberg-Bachmann or Cadogan reaction of diazotated chloroanilines-14C with different chlorobenzenes gave di, tri- and pentachlorobiphenyls-14C. By boiling anilinediazonium sulfate-14C the authors prepared phenol-14C, which was chlorinated to give 2,4,6-trichlorophenol-14C. Hexachlorobenzene-14C and pentachloronitrobenzene-14C were prepared by chlorination of nitrobenzene- 14C. Chloralkylene 9-14C was synthesized by Friedel-Crafts alkylation of 2,4'-dichlorobiphenyl-14C with 2-chloropropane.
