RT Journal Article T1 Evaluation of supercritical fluid chromatography accurate mass spectrometry for neonicotinoid compounds determination in wine samples A1 Pérez Mayán, Leticia A1 Cobo Golpe, María A1 Ramil Criado, María A1 Cela Torrijos, Rafael A1 Rodríguez Pereiro, Isaac K1 Neonicotinoids K1 Supercritical fluid chromatography K1 Wine analysis K1 Accurate mass spectrometry AB 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 been investigated. Thorough optimization of the different parameters (column, modifier, back-flush pressure, make up, etc.) affecting the SFC-MS selectivity and sensitivity was carried out. Under final conditions, a 2 mL volume of either red or white wine was extracted by SPE and analysed using external standard calibration achieving limits of quantification from 1 to 11 ng mL−1. Global recoveries ranged between 63 and 118%, depending on the compound and the spiked amount. When compared to UPLC performance, SFC resulted in a better separation of compounds, narrower peaks, comparable sensitivity and significantly lower matrix effects. The developed method allowed the quantification of imidacloprid in around half of the 25 commercial wine samples processed, all of them proceeding from grapes cultivated in year 2018 in the Northwest of Spain, with a maximum concentration of 33 ng mL−1. Acetamiprid was also detected in some white wine samples PB Elsevier SN 0021-9673 YR 2020 FD 2020 LK http://hdl.handle.net/10347/20872 UL http://hdl.handle.net/10347/20872 LA eng NO L.
