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 HomogenizersWhat 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)
