Peptide Analysis: Zwitterionic Chiral Ion-Exchangers as Complementary Option to HILIC and to Reversed-Phase Chromatography

Therapeutic peptides represent one of the fastest growing segments in the pharmaceutical market. To bring these products to the market in a consistent manner, high quality is a major concern and requires stringent quality control (QC) methods. This article discusses the potential of zwitterionic chiral ion-exchangers to support peptide analysis and quality control as a flexible complementary tool to monitor the stereochemical integrity and chemical modifications.
