Determination of pesticide residues in wine by solid-phase extraction on-line combined with liquid chromatography tandem mass spectrometry
Pérez Mayán, Leticia; Ramil Criado, María; Cela Torrijos, Rafael; Rodríguez Pereiro, Isaac (Elsevier, 2021)Liquid chromatography tandem mass spectrometry (LC–MS/MS) has been combined with different sample preparation strategies to determine potential pesticide residues existing in wine. Herein, we propose the on-line coupling ... -
Evaluation of supercritical fluid chromatography accurate mass spectrometry for neonicotinoid compounds determination in wine samples
Pérez Mayán, Leticia; Cobo Golpe, María; Ramil Criado, María; Cela Torrijos, Rafael; Rodríguez Pereiro, Isaac (Elsevier, 2020)The suitability of supercritical fluid chromatography, coupled to accurate mass spectrometry (SFC-MS), for the determination of seven commercial neonicotinoid pesticides and one transformation product in wine samples has ... -
Fabric phase sorptive extraction followed by ultra-performance liquid chromatography-tandem mass spectrometry for the determination of fungicides and insecticides in wine
Pérez Mayán, Leticia; Rodríguez Pereiro, Isaac; Ramil Criado, María; Kabir, Abuzar; Furton, Kenneth G.; Cela Torrijos, Rafael (Elsevier, 2019)In this work, fabric phase sorptive extraction (FPSE) is investigated for the extraction and preconcentration of ultra-trace level residues of fungicides (19 compounds) and insecticides (3 species) in wine samples. ... -
Multiresidue procedure to assess the occurrence and dissipation of fungicides and insecticides in vineyard soils from Northwest Spain
Pérez Mayán, Leticia; Ramil Criado, María; Cela Torrijos, Rafael; Rodríguez Pereiro, Isaac (Elsevier, 2020)The presence of fungicide and insecticide residues in wine has been largely investigated. However, few studies have addressed the persistence of these compounds in vineyard soils. In this research, we investigate the ... -
Residues of anilinopyrimidine fungicides and suspected metabolites in wine samples
Castro Varela, Gabriela; Pérez Mayán, Leticia; Carpinteiro Botana, María Inmaculada; Ramil Criado, María; Cela Torrijos, Rafael; Rodríguez Pereiro, Isaac (Elsevier, 2020)The coexistence of the anilinopyrimidine fungicides pyrimethanil (PYR) and cyprodinil (CYP), and suspected metabolites in wine samples was investigated by liquid chromatography (LC) with tandem mass spectrometry (MS/MS), ...
