Abstract
This study was performed to compare the analytical results among L2000DX and two GC/ECD methods (rapid and conventional). 15 samples of transformer oils were collected to compare the analytical results. In the analytical results of PCBs-containing transformer oil, the PCBs concentrations were in the range of 4.4mg/L to 182.8 mg/L with L2000DX, N.D. to 14.63 mg/L with conventional GC/ECD, and N.D. to 13.03 mg/L using rapid GC/ECD. The PCB concentrations detected with the L2000DX showed a large difference to those detected with GC/ECD methods. Otherwise, little difference was shown between the two GC/ECD methods at a concentration range lower than 4 mg/L, although the rapid GC/ECD method tended to detect a slightly lower concentration near the regulation criteria of Korea for 2 mg/L.
