A method for the analysis of carbendazim in peper has been developed usingSupercritical Fluid Extraction (SFE) for the sample preparation and the combinationof Laser Desorption (LD) with Resonance Enhanced Multi-Photon Ionization (REMPI)coupled to Time-of-Flight Mass Spectrometry (TOF-MS) for the detection. The methodallows the analysis of carbendazim in pepper reducing the sample preparation step andavoiding the matrix effects present in classical GC and HPLC techniques, as well as theproblems related to the labile properties of carbendazim. The detection limit obtained isof the same order of magnitude as the generally employed HPLC technique, but withhigher sensitivity and easier sample preparation.
