The removal of interferences and sample concentration are
essential steps in trace level detection of pesticides, sheep
dips, herbicides and PCBs in river water, wastewaters and
trade effluents. The following methods were developed by
the Environment Agency National Laboratory Service facility
at Nottingham using the Biotage RapidTrace for automated
solid phase extraction and the TurboVap II for evaporation.
The procedures are UKAS accredited and can reach detection
limits of 0.001 ug/Litre for some compounds.

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.

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.

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.
