USEPA method 608 is a GC-ECD method to determine Aroclor and organochlorine pesticides. This method requires the use of second column for confirming the detected compounds due to the low selectivity of the ECD detector compared with GC-MS/MS. Also pattern recognition is required for accurate identification of Aroclors. A triple quadrupole GC-MS/MS based method offers a solution for the GC-ECD method’s drawbacks by providing high selective analysis. In addition, the type and concentration of Aroclor can be simultaneously determined. In this report, the performance of this new analytical method is demonstrated using environmental samples.
