A liquid chromatography-tandem mass spectrometry method for the quantitative determination of fumonisin FB1 FB2 and their respective hydrolysed metabolites HFB1 and HFB2 in pig liver has been developed and validated The method was based on an easy extraction procedure followed by SPE purification Chromatographic separation of the analytes was performed on a C18 column using 0 3% of formic acid in water and acetonitrile as elution solvent The mass spectrometer operated in the positive electrospray ionisation mode (ESI+) using multiple reaction monitoring (MRM) An intralaboratory validation was carried out with fortified samples for determining precision trueness specificity limit of detection (LOD) and limit of quantification (LOQ) The method showed good performance characteristics and proved to be sensitive selective and reliable The LOD was 005 ng g(-1), and the LOQ was 10 ng g(-1) for all the analytes The developed method has been applied to seven pig liver samples in order to test its applicability to evaluate exposure of food animals to fumonisins (C) 2010 Elsevier Ltd All rights reserved
