| Abstract: | Different 2,3,7,8-substituted polychlorinated dibenzodioxins (PCDDs) and dibenzofurans (PCDFs) were investigated for their retention behaviour on a disposable minicolumn containing activated carbon AX-21. Elution behaviour and recovery were examined, using native and radiolabelled PCDD and PCDF isomers. A comparison of the total mass chromatograms of PCDDs and PCDFs in an extract from animal adipose tissue, before and after activated carbon treatment, demonstrates the efficiency of this cleanup step with respect to the elimination of interfering compounds. |
