| Popis: | The retention characteristics of a novel pH tunable water stationary phase are presented. The method utilizes a change in mobile phase from N2 to CO2 to acidify the water phase in situ and control the ionization and elution of organic acids. With N2 present the phase pH > 5.4 and the acids are ionized and strongly retained. Conversely, with CO2 present the pH |
