A new and rapid HPLC method which allows the simultaneous determination of 15 pesticides in wine has been developed. A satisfactory pesticide separation was achieved with an RP18 column and water-acetonitrile (50:50 v/v) as the mobile phase. The limit of detection ranged from 0.006 to 0.020 ppm. The method does not require extraction of active ingredients from wine but uses C8 solid-phase extraction cartridges, which allow purification and concentration of the sample. With this extraction procedure, recoveries of pesticides at 0.01-0.02 and 1.00 ppm ranged from 85 to 108%.

Abstract
A new and rapid HPLC method which allows the simultaneous determination of 15 pesticides in wine has been developed. A satisfactory pesticide separation was achieved with an RP18 column and water-acetonitrile (50:50 v/v) as the mobile phase. The limit of detection ranged from 0.006 to 0.020 ppm. The method does not require extraction of active ingredients from wine but uses C8 solid-phase extraction cartridges, which allow purification and concentration of the sample. With this extraction procedure, recoveries of pesticides at 0.01-0.02 and 1.00 ppm ranged from 85 to 108%.
