"An Ultrasound-Vortex-Assisted Dispersive Liquid-Liquid Micro-Extraction (USVADLLME) procedure coupled with Gas Chromatography-Flame Ionization Detector (GC-FID) or Gas Chromatography-Ion Trap Mass Spectrometry (GC-IT\/MS) is proposed for rapid analysis of six phthalate esters in hydroalcoholic beverages (alcohol by volume, alc vol−1, ≤ 40%). Under optimal conditions, the enrichment factor of the six analytes ranges from 220 to 300 fold and the recovery from 85% to 100.5%. The limit of detection (LOD) and limit of quantification (LOQ) are ≥ 0.022 μg L−1 and ≥ 0.075 μg L−1, respectively. Intra-day and inter-day precisions expressed as relative standard deviation (RSD), are ≤ 8.2% and ≤ 7.0%, respectively. The whole proposed methodology has demonstrated to be simple, reproducible and sensible for the determination of trace phthalate esters in red and white wine samples"
