New reversed stationary phases applied to separation of selected biologically active compounds

Abstract

Modern reverse stationary phases were used for separation of some nonapetides. Retention behaviour of studied nonapeptides was compared on two silica-based columns (Supelcosil LC-18-DB, Discovery HS F5) and one zirconia-based column (Discovery Zr-PBD).
