Alle ansehen Thermo Scientific ProdukteBeschreibung
Use Thermo Scientific™ QuEChERS Clean-up 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 AOAC 2007.01 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.
QuEChERS AOAC 2007.01 Method Clean-up Kits
These kits use dispersive solid phase extraction (dSPE) to purify supernatants obtained during extraction. Clean-up kits are available in prefilled 2 mL and 15 mL tube formats for the following matrices: general fruits and vegetables, pigmented fruits and vegetables, fruits and vegetables containing fats and waxes, and all other food types.
Chemicals used in the AOAC 2007.01 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; removes remaining water from sample during dSPE
- NaOAc: 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 during dispersive solid phase extraction
- C18: removes fats, sterols, and other non-polar interferences from sample
- GCB: graphitized carbon black, removes pigment (not recommended for use with planar pesticides)
