This application note was developed for the clean-up of a non-polar solvent extract of vegetable material. The methodology is applicable to a wide range of organochlorine and organophosphorus pesticides and a number of vegetable types. The analytes are relatively non-polar, and will not be strongly retained by polar/anion exchange sorbents.

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.

This technical note describes the use of layered SPE columns in applications where multiple suites of analytes with a broad polarity range are to be extracted simultaneously from a single water sample, such as organochlorine, triazine and organophosphate pesticides, or endocrine disrupters.
