A simple and fast method was developed for the simultaneous determination of 75 plastic food contact material (FCM) substances in liquid food simulants, at levels of a few ng g-1. The method employs an optimised Salt-Assisted Liquid-Liquid Extraction for all EU regulated ethanol/H2O food simulants, in the presence of 10 % NaCl (simulants A and C) or 5 % m/v NaCl (simulant D1), and dichloromethane as the extracting solvent. Gas chromatography with triple-quad MS operating in multiple reaction monitoring acquisition was used, applying isotope dilution with selected deuterated compounds. Adequate sensitivity was demonstrated for all analytes. The results also showed sufficient accuracy for the majority of substances, with recoveries between 70–120 % and repeatability (expressed as relative standard deviations, RSDs) smaller than 15 %. The method was applied to the analysis of FCM multilayer items after undergoing migration testing according to the specifications of the current EU 30 legislation in force.
