Determination of Pesticides in Red Wine by QuEChERS extraction, novel Clean-up with Rapid Mini-cartridge Filtration and LC–MS–MS
Xiaoyan Wang and Michael J. Telepchak
A novel, simple, rapid and effective method was developed to determine pesticide residues in red wine samples. Sample preparation involved extraction of pesticide residues into acetonitrile by QuEChERS and clean-up with a rapid push-through mini-cartridge filter instead of dispersive phase extraction.
