Abstract
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 values obtained by liquid chromatography on the Hypercarb carbon sorbent. Relationships between the calculated values of TCA and experimental retention values were shown.
