QuEChERS Multiresidue Pesticide Method for Wine
Pesticides are extracted using acetonitrile saturated with magnesium sulfate and sodium chloride followed by a dispersive solid-phase cleanup with primary-secondary amine (PSA) and graphitized carbon black (GCB) sorbents. Analysis is performed using ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) in ESI mode
