[Testing of residues of vegetable drugs, organochlorine herbicides and polychlorinated biphenyls (PCB)].

According to the establishment of methods for the determination of PSM residues in vegetable drugs the authors tried to detect organo-chlorinated compounds, which are used in agriculture and industry thus becoming of interest for the quality control of vegetable drugs. In most of the cases the determination was carried out by liquid/liquid partition between acetonitrile/n-hexane in combination with the CC using florisil for sample purification and capillary GC with a methyl silicone rubber column. Some of the results required a confirmation using a Megabore D-608 column (J&W Scientific).
