EPA Method 8141B describes the performance based procedure to determine low ppb levels of organophosphorous pesticides in ground water.
The OP pesticides are extracted using solid phase extraction (SPE) based on the procedure outlined in Method 3535A for OP pesticides by Method 8141. The analysis is performed with capillary GC using a FPD
(flame photometric detector). This initial demonstration of capability was conducted using the Biotage® Horizon 4790 Automated Extractor System.
