VALIDATION OF A HIGH PERFORMANCE LIQUID CHROMATOGRAPHY METHOD FOR CARBENDAZIM RESIDUES QUANTIFICATION IN TOMATOES

Abstract

A high performance liquid chromatography method for carbendazim residues determination was adapted to the condition of our laboratory and validated for tomatoes samples. Carbendazim eluted at 3.13 minutes. The signal was linear over the concentration range 1 to 15 µg/ml with correlation coefficient 0.999092. The detection limit and the quantitation limit values were 0.002 mg/kg and 0.02 mg/kg respectively. Relative standard deviation of repeatability was 3.47% and 4.78% and recovery was 99.67% and 113,11% for two levels of concentration. The adapted method allowed a simple and rapid separation and quantification of carbendazim in tomatoes by high performance liquid chromatography.
