  • Title: Determination of carbendazim residues in fruit juices by liquid chromatography-tandem mass spectrometry.
    Author: Grujic S, Radisic M, Vasiljevic T, Lausevic M.

    Abstract:
    In this paper a rapid optimized method for routine analysis of carbendazim residues in fruit juices is reported. The procedure is based on matrix solid-phase dispersion (MSPD) with diatomaceous earth and analysis of the extract by liquid chromatography-tandem mass spectrometry, with electrospray ionization (LC-ESI-MS/MS). In the method optimization, finding of the optimal pH for the extraction of carbendazim from juice was particularly critical. Significant matrix effects were observed, but could be eliminated using matrix-matched standards. High recoveries (82-102%), good repeatability (RSD<or=12%) and low limits of detection (0.03 ng ml-1) and quantification (0.1 ng ml-1) were achieved with this method.
