title: New polymer-based prepacked column for the reversed-phase liquid chromatographic separation of peptides over the pH range 2-12.
abstract: The aim of this paper was to investigate the properties of a new column, Source 5RPC, for the separation of peptides at pH 2, 4.5, 7, 9 and 12 and to compare this product with similar polymer-based products available on the market. All columns were prepacked with 5 microm polystyrene-divinylbenzene polymer bead matrices and had dimensions of 150x4.6 mm I.D. Separations of angiotensin peptides were achieved on these columns using different equilibration solvents in the pH range 2-12 and elution with acetonitrile gradients. The separation of the peptide mixture obtained on Source 5RPC column was compared with that of two other commercially available polymer-based matrices. Method scouting and optimisation were carried out using the novel chromatography system, AKTA purifier.
