QuEChERS AOAC 2007.01 Method Clean-up KitsThese 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)
