High-throughput gas chromatography-mass spectrometry analysis of pesticide residues in spices by using the enhanced matrix removal-lipid and the sample dilution approach

Autor: Elena Hakme, Samanta Uclés, Ana Lozano, María del Mar Gómez-Ramos, Amadeo R. Fernández-Alba

Publikováno v: Journal of Chromatography A. 1573:28-41

Spices are known as difficult matrices that contain variable amounts of fats, piperine or many other matrix constituents. The increasing sensitivity of new GC–MS/MS platforms opens new approaches to analyze pesticide residue in complex matrices suc

Shifting the paradigm in gas chromatography mass spectrometry pesticide analysis using high resolution accurate mass spectrometry

Autor: M.J. Martínez Bueno, Ana Lozano, Samanta Uclés, Ana Uclés, Amadeo R. Fernández-Alba

Publikováno v: Journal of Chromatography A. 1501:107-116

In the last 10 years, the majority of the pesticide food control laboratories moved from GC-MS to GC-MS/MS as the preferred analytical technique to address GC amenable compounds. The main reason for this change was the negative impact on the single s
