AOAC Method 983.15 was developed to assay levels in finished food products. This method specifies a C18 column that provides suitable selectivity in many cases, but sometimes there can be matrix interferences. In this work the Thermo Scientific Accucore Polar Premium HPLC column, provides the speed, efficiency, and alternate selectivity to resolve propyl gallate from the unknown matrix peak.

The Thermo Scientific Accucore C18 column was used to assay antioxidants in finished food products based on method AOAC Official Method 83.15.

The Thermo Scientific Ultimate 3000 system is applied for the improved separation of fat-soluble vitamins. The Thermo Scientific Acclaim RSLC PolarAdvantage column separated nine vitamins with a run time of less than 20 minutes.

The Thermo Scientific Dionex UltiMate 3000 RSLC system is applied for the determination of fat soluble vitamins. The separation is performed on a Thermo Scientific Accucore XL C18 HPLC column, with UV detection at 280 nm. Compared to a conventional 5 μm fully porous column using the same experimental conditions, the Accucore XL C18 4 μm HPLC column provides improved efficiency and resolution.

The Thermo Scientific HPLC system is applied for the analysis of fat soluble vitamins. The separation is performed on a Thermo Scientific Hypersil GOLD HPLC column in less than 8 minutes, with UV detection at 280 nm.
