摘要：

The analysis of polychlorodibenzodioxins and polychlorodibenzofurans on a novel multidimensional (CGC-CGC-MS) configuration is presented. The system is based on flow controlled column switching, allowing the simultaneous isomeric separation of tetrachloro-, pentachloro- and hexachloro-substituted dibenzodioxins and dibenzofurans on a polar column and the analysis of heptachloro- and octachloro-substituted dibenzodioxins and dibenzofurans on an apolar column. PTV injection in the solvent vent mode allows analysis of large sample sizes approaching in this way the sensitivity of CGC - high resolution MS.
