The purpose of this study was to develop a faster analysis method of PCBs in transformer oil and to compare this to the Korean official method. The Korean official method is composed of 4 steps; alkaline digestion, sulfuric acid extraction, clean-up with silica-gel column, and concentration by nitrogen blowing. On the other hand, the proposed fast PCBs analysis method is composed of simpler steps; one-step column separation (Rapiana)and the following concentration by nitrogen blowing. Both methods were compared by analyzing same samples including CRMs. GC/ECD equipped with dual column was used for PCBs analysis. PCB-189 and PCB-209 were used as surrogates and TCMX (tetrachloroxylene) was used as internal standard. Surrogate recovery (75-120%) obtained by the proposed fast analysis method turned out to be better than that of the Korean official method (63-85%). The fast PCBs analysis method is faster than the Korean official method (3hours vs 20 hours) and also can save labor and analysis cost.
