The retention of glycine-based peptides on a Hypercarb carbon adsorbent is studied by reversed-phase HPLC. In the reaction mixture obtained in the synthesis of polyglycines, ions corresponding to both linear and cyclic peptides are detected by electrospray ionization mass spectrometry. Characteristics of the retention of the components are determined on varying the composition of the mobile phase...
The retention of peptides with protected functional groups on the Hypercarb carbon sorbent was studied by reversed phase HPLC. The peptides were identified by tandem mass spectrometry with electrospray ionization. The thermodynamic characteristics of adsorption (TCA) of the peptides on the graphitized thermal carbon black were determined by the molecular statistical method and compared with the retention...
