摘要

The retention of a diastereomeric pair of peptide analogs was investigated as a function of temperature using reversed-phase HPLC. The retention of these compounds showed anomalous behavior with retention increasing with increasing temperature. The change in the compounds' pK_a as temperature was varied was measured chromatographically and decreases with increasing temperature. The change in degree of ionization as a function of temperature was used to explain this anomalous retention behavior.
