Determination of Method 608 Organochlorine Pesticides and Polychlorinated Biphenyls Using GC-MS/MS Operated in the MRM Mode
Author(s)Shimadzu Corporation
This application news presents instrument operating conditions and instrument method performance statistics, including method linearity, accuracy, and precision, for priority pollutant pesticides and PCB congeners. The method validated in this application acted as guidance in developing ASTM D8543 Test Method for Determination of OCPs and PCBs in Aqueous Solution by a GC/MS/MS which is intended for proposal to EPA as an alternative test procedure (ATP) for EPA 608.3
