Use Thermo Scientific™ QuEChERS Extraction Kits to prepare complex sample matrices such as fruits and vegetables for LC-MS or GC-MS analysis of pesticide residues, veterinary drug residues, and toxins using the EN 15662 Method. Our QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) kits contain pre-packaged, ready-weighed salts, sorbents, and buffers designed to streamline your workflow, provide excellent recoveries for a wide variety of analytes, minimize the potential for error, save time and money, and deliver high-quality, reproducible results.

Thermo Scientific™ QuEChERS EN 15662 Method Extraction Kits make sample preparation straight-forward and efficient, enabling you to confidently perform extractions and analyze fruit and vegetable samples for pesticide residues and other contaminants.

Three different extraction kit formats are available for 10 g samples.

  • Extraction Salts in Pouches, no Tubes
  • Extraction Salts in Pouches with 50 mL Tubes
  • Extraction Salts in Pouches with 50 mL Tubes and Ceramic Homogenizers

What is the purpose of the chemicals used in the EN 15662 Method?

  • Acetonitrile: used to perform single-phase extraction on a sample
  • Anhydrous MgSO4: induces phase separation between water content in sample and acetonitrile layer; removes remaining water from sample
  • NaCl: induces phase separation between water content in sample and acetonitrile layer; removes residual water from sample
  • Trisodium Citrate: buffers the sample to stabilize pH
  • Disodium Citrate Sesquihydrate: buffers the sample to stabilize pH
  • PSA: primary secondary amine, used to remove polar matrix components, citric co-extractives, and free fatty acids, from sample
  • C18: removes fats, sterols, and other non-polar interferences from sample
  • GCB: (graphitized carbon black) removes pigment (not recommended for use with planar pesticides)
