Abstract Prcedures for the discrimination between polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs) taken from the literature are discussed. It is demonstrated that the analysis of mixtures of PCBs and PCNs can conveniently be accomplished by both high-performance liquid and gas chromatography, after their conversion into the fully chlorinated end-products, viz ., decachlorobiphenyl and octachloronaphthalene, respectively. Succesful analyses of Halowx 0151, which is a mixture of octa- and heptachloronaphthalenes, are also reported.

High-performance liquid and gas chromatography can effectively distinguish between polychlorinated biphenyls and polychlorinated naphthalenes, with successful analyses of Halowx 0151.

Discrimination between polychlorinated naphthalenes and polychlorinated biphenyls

Key Takeaway: High-performance liquid and gas chromatography can effectively distinguish between polychlorinated biphenyls and polychlorinated naphthalenes, with successful analyses of Halowx 0151.
