The document describes a fast method for the analysis of synthetic antioxidants in vegetable oils. The method uses the Agilent 1290 Infinity LC system equipped with an Agilent ZORBAX Rapid Resolution High Definition (RRHD) column and achieves high throughput in 2 minutes with a backpressure of 1120 bar, which is below the 1200 bar upper limit of the column. Optimization of the mobile phase composition and the temperature are discussed. The figures of merit are illustrated using standard solutions and spiked vegetable oil (sunflower, rapeseed, and olive) extracts. Limits of detection are 1 mg/kg or less in the oil samples. Using a simple methanol extraction, good recovery was obtained for all antioxidants in the oil samples.
