Quantification of Dioxin-Like Polychlorinated Biphenyls Using GCxGC-ECD with a Selective Column in the Second Dimension

GCxGC-ECD with a selective column in the second dimension offers a way to substantially improve separations for the important group of dioxin-like PCBs, even in the presence of PCBs that are normally at higher concentrations in environmental samples. Due to the increase in peak capacity afforded with GCxGC, organochlorine pesticides did not interfere with dioxinlike PCB determinations either.
