Thermo Scientific™ QuEChERS Original 2003 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 for pesticide residues, veterinary drug residues, and toxins using the Original 2003 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 Original 2003 Method Extraction Kits make sample preparation straight-forward and efficient
• With our QuEChERS kits, you can confidently perform extractions and analyze fruit and vegetable samples for pesticide residues and other contaminants
• Three different extraction kit types are available to support the Original 2003 QuEChERS Method
• Extraction Salts in Pouches, no Tubes – for 10 g or 15 g samples Extraction Salts in Pouches with 50 mL Tubes – for 10 g or 15 g samples Extraction Salts in Pouches with 50 mL Tubes and Ceramic Homogenizers – for 10 g or 15 g samples What is the purpose of the chemicals used in the Original 2003 Method? Acetonitrile: used to perform single-phase extraction on a sample Anhydrous MgSO4: induces phase separation between water content in sample and acetonitrile layer during liquid-liquid partitioning step; removes remaining water from sample during dispersive solid phase extraction (dSPE) step NaCl: induces phase separation between water content in sample and acetonitrile layer during liquid-liquid partitioning step; removes residual water from sample; reduces polar interference and enhances extraction PSA: primary secondary amine, used to remove polar matrix components, citric co-extractives, and free fatty acids, from sample during dispersive solid phase extraction (dSPE) step
