Rapid Extraction and Analysis of Pyrethroids from Sediments by QuEChERS and LC/MS/MS (TN-0098)

Presented is a modified version of the QuEChERS method to extract pyrethroids from marine and river sediment samples followed by Liquid Chromatography-Tandem Mass Spectrometry (LC/MS/ MS) analysis. The result is a rapid, simple, and efficient extraction and analysis of 7 pyrethroids with reporting limits in the low ng/g range. The use of the modified extraction and clean up method resulted in higher sample throughput, faster extraction times, and greatly reduced solvent consumption compared to conventional solid matrix extraction methods.
