New capillary gas chromatography column for the simultaneous isomer-specific analysis of 2,3,7,8-TCDD and 2,3,7,8-TCDF

Abstract A new capillary gas chromatography (GC) column has been developed that resolves both 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and 2,3,7,8-tetrachlorodibenzofuran (TCDF) from all of their other respective tetrachlorinated isomers, and permits determination of both of these compounds in a single gas chromatography-mass spectrometry (GC-MS) analysis.
