| Abstract | A model has been developed which successfully predicts the order of elution and relative retentions of tetra-, penta- and hexachloro-dibenzo-p-dioxins for gas chromatography (GC) columns of different polarity. These congeners include the most toxic 2,3,7,8-substituted isomers, and contain numerous difficult-to-separate isomers. The model allows the correlation of GC retention time to dioxin substitution pattern. The model also allows the prediction of dioxin elution order and relative retention time spacing for GC columns of different polarity. (Copyright (c) 1992 Elsevier Science Publishers B.V.) |
