Six activated charcoals were tested, using a multidimentional GC separation technique, for their efficiencies to isolate the most toxic, non-ortho Cl substituted biphenyls (CBs) from ortho Cl CBs in order to allow their reliable determination by single column GC-ECD. The tested charcoals failed to meet the requirement of complete separation of these groups of CBs. In addition interfering non-CB compounds were found to elute from charcoals.
