Red wine is a rich source of phenolic antioxidants and is reported to reduce the risk of diabetes, cancer, Alzheimer's disease, and cardiovascular disease. To improve grape yields it is common practice in vineyards to use pesticides, such as fungicides and insecticides. This application presents a fast, easy, and cost-effective method for the determination of 24 pesticide residues in red wine using the QuEChERS extraction method (AOAC version), cleanup by dispersive solid-phase extraction (dSPE), followed by LC-MSMS analysis.
The Thermo Scientific UltiMate 3000 HPLC system is applied for the determination of 24 pesticide residues in red wine. The samples are prepared using Thermo Scientific HyperSep Dispersive SPE (QuEChERS), and the separation performed using a Thermo Scientific Accucore aQ HPLC column, with MS/MS detection.
