AOAC 2007.01 with modifications
Pesticides in this screen are extracted using modifications of the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) method. The QuEChERS method, originally developed by the FDA and USDA, is an AOAC Official Method (2007.01). Modifications were necessary for the extraction of pesticides in dry commodities (J. Agric. Food Chem, 2010, 58, 5959-5972) and high fat commodities (J. Agric. Food Chem, 2010, 58, 5950-5958). A mixture of acetonitile and water (for dry commodities) or acidified acetonitrile (for high moisture fruits, vegetables and other samples with high water content), is used to extract any pesticide residue from the sample. The sample and solvent(s) are then treated with an extraction media to isolate the pesticide residues in the acetonitrile. The extract is cleaned using dispersive solid phase extraction. Cleaned extracts are analyzed by Capillary Gas Chromatography Time of Flight Mass Spectrometry (GC/TOFMS),Ultra Performance Liquid Chromatography Tandem Mass Spectrometry (UPLC/MSMS) and Gas Chromatography Tandem Mass Spectrometery (GC/MSMS). Identification, confirmation, and quantification are performed using both technologies. Sample extracts are compared against a matrix matched standard. Method and Instrument Performance standards are analyzed with each sample to ensure quality results.
Information Required by Submitter:
Please provide fat estimates.
*** Please do not write with a marker or Sharpie on the sample or sample packaging as this may contaminate the sample and affect the results. ***
Certain analytes may be excluded from a screen due to specific matrix interference; for a complete list, please contact a Medallion Labs representative.
The analytes found in the Expanded Screen are chosen based on customer requests and national and international regulatory requirements.
