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.

EPA methods 8260 & 8270 cover the analysis of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in ground & surface waters. This also now includes 1,4-dioxane and PCBs. This application note will focus on the automated SPE of the sample rather than the detection which usually involves GCMS or LCMS. NB The columns and reagents used for soils and sediment analysis differ to ground water extraction.

This study shows that the Biotage® 4790 Automated Extractor system, along with the Atlantic™ DVB disk, the DryDisk® separation membrane, and the DryVap® Concentrator System can be successfully used to analyze for Nonyl Phenol and Bisphenyl A in water samples. This sample preparation process is fully automated, requiring minimal human intervention, and allowing for reductions in sample processing costs.
