✦ Synopsis


All common phenyhhiohydantoin amino acids derived from sequencing are identifiable in 6 to 9 min with an isocratic method based on buffered aqueous acetonitrile, an ODS stationary phase, and programmed flow which increases during the run. With constant flow the analysis requires 16 min. The effects of variation in percentage eluting solvent, ionic strength, anion, cation, pH, and temperature are defined.
