[Analysis of residues of organochlorine compounds in plant drugs. 3. Identification of residues of polychlorobiphenyl compounds by comparison of gas chromatography on packed and capillary columns and GCMS coupling].

The identification of residues of polychlorinated biphenyls in a test sample of Flores Chamomillae could be achieved by the retention behavior at gas chromatographic analyses on packed and capillary columns compared with reference standard Clophen A 60, respectively as well as well by capillary GC/MS using single ion monitoring of substance-characteristic ion mass.
