Abstract

Isomer differentiation of chlorinated dibenzo-p-dioxin (CDD) isomer pair components was examined by three orthogonal chromatographic (gas chromatography, liquid chromatography, and micellar electrokinetic chromatography) techniques and three orthogonal spectroscopic (Fourier transform infrared and carbon-13 and proton nuclear magnetic resonance) techniques. Synthetic CDD isomer pair mixtures from the same sample set were separated by methods using independent partitioning dynamics and identified by spectroscopic methods using independent energy/structure transformations. This integrated approach using orthogonal methods minimizes isomer identification error probability and results in an excellent agreement among methods in isomer assignment.
