This application note was developed to demonstrate the extraction of five organophosphate compounds Monocrotophos, Diazinon, Malathion, EPN, and Methamidophos using one solid phase extraction method with one pre-treatment step of sodium chloride (NaCl). The method uses the Biotage® Horizon 4790 automated SPE extraction system. It will show the efficiency of the extraction while demonstrating excellent recoveries of OPP compounds using methylene chloride and minimal amounts of acetone after sample pre-treatment with sodium chloride. Methods were developed and results are shown using 47 mm Atlantic® HLB-H disks and carbon cartridges.

Method 1657 describes the procedure to determine low ppb levels of organophosphorus pesticides in municipal and industrial wastewater.
The City of Fort Worth Water Department implemented Automated SPE for the analysis of organophosphorous pesticides by EPA Method 1657, using the Atlantic™ C18 solid phase extraction disk.
The Biotage® Horizon 4790 Automated Extraction System with Envision®
Platform controller, and the DryVap® Automated Drying
and Concentration System were used in this application note.

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.

In postmortem cases, where drugs or pesticides have been used for
their poisonous properties, traditional matrices such as urine and
whole blood may be inappropriate for qualitative and quantitative
analysis. As the site of metabolism for most drugs and toxins, the
liver may provide more insight to cause of death than other bodily
This poster describes the use of ISOLUTE SLE+ supported liquid extraction columns to extract a range of drug and pesticide classes form homogenised liver using a simple, streamlined workflow.

This application note describes the extraction of a broad range of analytes from liver tissue matrix prior to GC/MS analysis using ISOLUTE® SLE+ supported liquid extraction columns.
A protocol has been developed that allows the simultaneous
extraction of various drugs of abuse classes: amphetamines, barbiturates, benzodiazepines, cocaine, ketamine, THC.
In addition to these drug panels, simultaneous extraction of carbamate, organochlorine, organophosphate, pyrethroid, and triazine pesticide classes is demonstrated.
