Abstract:
Reversed-phase high-performance liquid chromatography (RP-HPLC) is of fundamental importance to the isolation and separation of peptides, proteins, and other biomolecules. Hence, there is a continuing high demand for the development of RP-HPLC stationary-phase materials with enhanced separation efficiency. HALO packing materials began the revolution in "core-shell" technology with the advantages of faster separations, higher resolution and peak capacity, high temperature stability, and rugged reliable performance compared to traditional HPLC and UHPLC. These materials are characterized by a solid core surrounded by a thin layer of porous material, and represent a technology for the future with continuing refinements. Such refinements are aided via the use of designed synthetic peptide standards during stationary-phase development. Concomitantly, such standards also enable the researcher to monitor RP-HPLC column performance and develop optimized separation protocols for peptides from a wide array of sources. © 2016 by John Wiley & Sons, Inc.
