Abstract
AbstractThe simultaneous HPLC determination of carbendazim, thiabendazole and thiophanate‐methyl in apples, pears and their pulps is described. The method is based on a clean‐up procedure carried out on an Extrelut 20 cartridge followed by HPLC analysis on a Diol column using hexune+isopropanol as mobile phase. Average recoveries of 83.8% for carbendazim, 82.9% for thiabendazole and 68.8% for thiophanate‐methyl on apple matrix were obtained; recoveries on pear matrix were in the same range. Detection limits with UV detection at 285 nm of 100 ng ml−1 for carbendazim, 140 ng ml−1 for thiabendazole and 500 ng ml−1 for thiophanate‐methyl were achieved.
