Apple extract is a complex mixture of polyphenols, vitamins and amino acids. Analysis of this mixture is performed by mixed-mode chromatography. Different selectivity is achieved on two different columns: Primesep 200 reversed-phase cation-exchange column, and Primesep D reversed-phase anion-exchange HPLC column. Compounds are monitored by UV detection. Methods are compatible with LC/MS and preparative chromatography and can be used for identification and isolation of specific compounds.
The Primesep family of mixed-mode columns offer a wide variety of stationary phases with an unprecedented selectivity in the separation of a broad array of chemical compounds and in multiple applications. Corresponding Primesep guard columns are available with all stationary phases and do not require holders. SIELC offers a method development service which is available for all customers. Ask about our special custom LC-phases tailored for specific separations.
