Thermo Scientific™ QuEChERS EN 15662 Method Extraction Kits

Description

• 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)
