AN320: Extraction of Chlorinated Pesticides Using Accelerated Solvent Extraction (ASE)
Instrument Type: Automated Sample PrepAccelerated Solvent Extraction (ASE®) is an extraction method that significantly streamlines sample preparation. The procedures described in this application note meet the requirements for sample extraction as prescribed by EPA Method 3545. This method is applicable to the extraction of water-insoluble or slightly water-soluble volatiles and semivolatiles in preparation for gas chromatographic or GC/MS measurement. The method is applicable to the extraction of chlorinated pesticides from soils, clays, wastes, and sediments containing from 5 to 250 μg/kg of the target compounds.
Analysis of total organic carbon (TOC) by GC-MS
Instrument Type: GCMSIn this work the suitability and selective performance of the Thermo Scientific TraceGOLD TG-5SilMS for the analysis of total organic carbon was demonstrated. TOC can be used as a useful measure of the broad estimation or residual pesticides and other carbonaceous material. It is especially useful when coupled to mass selective detection as it allows identification and quantification of specific contaminating materials. Note the retention times in the component table match the component number and are not the actual retention time.
Excellent performance of the Thermo Scientific TraceGOLD TG-5SilMS GC column for the analysis of chlorinated pesticides by GC-MS
Instrument Type: GCMSIn this work the suitability of the Thermo Scientific TraceGOLD TG-5SilMS column for conformational identification of chlorinated pesticides when using US EPA methods 608, 617 and 8080 is demonstrated.
