Polystyrene matrix HPLC column

Gel permeation chromatography (GPC)/normal-phase HPLC was used by Brown-Thomas et al. (35) to determine fat-soluble vitamins in standard reference material (SRM) samples of a fortified coconut oil (SRM 1563) and a cod liver oil (SRM 1588). The on-line GPC/normal-phase procedure eliminated the long and laborious extraction procedure of isolating vitamins from the oil matrix. In fact, the GPC step permits the elimination of the lipid materials prior to the HPLC analysis. The HPLC columns used for the vitamin determinations were a 10 im polystyrene/divinylbenzene gel column and a semipreparative aminocyano column, with hexane, methylene chloride and methyl te/t-butyl ether being employed as solvent. [Pg.232]

Hypercrosshnked polystyrenes proved to be unique HPLC column packing materials (Chapter 13), adsorbents for sofid-phase extraction (Chapter 14), hemosorbents (Chapter 15), and a matrix for hypercrosslinked ion-exchange resins (Chapter 16). [Pg.669]
