We investigated a simplified determination of dymron in agricultural products by HPLC with UV detection.
Homogenates of agricultural products were extracted with acetone. Each crude extract was purified on Bond Elut® extraction Cartridge PSA and SAX using a mixture of acetonitrile and diethyl ether. Dymron was analyzed by HPLC with UV detection (243nm). The HPLC separation was performed on a ODS column with acetonitrile-water (50:50) as the mobile phase.
Recoveries of dymron from several agricultural products fortified at the level of 0.10ppm were in the range of 93.3-105.2%. The limit of detection was 0.005ppm in samples.
