The three different methods(Korea:I, EPA:II, Japan:III) of PCBs analytical methods were compared using 62 kinds of PCBs isomers. To do this, the cleanup process considered before proceeding the established each methods. The 2,3,4,4',5-PeCB(IUPAC No. 114) showed the lowest recovery, but 2,2‘,3,4,5’-PeCB(IUPAC No. 87), 2,2',3,3',4,4',5-HpCB(IUPAC No. 170) and 2,2‘,3,3’,4,4‘,5,5’ -OcCB(IUPAC No. 194) were represented the recoveries over 120% in 62 PCBs isomers. The recovery ranges following the number of Cl were obtained 68.54%(8 Cl)～95.69%(10 Cl) for Korea, 41.50% (1 Cl)～101.00%(10 Cl) for USA, and 68.30%(8 Cl)～89.53%(4 Cl) for Japan. Also, the average recoveries of 14 kinds coplanar-PCBs were obtained 79.69% for method I, 88.05% for method II and 73.38% for method III.
