Alternatively stronger acids and bases have been analyzed alongside hydrophobic analytes using mixed-mode chromatography in recent times. Reversed-phase HPLC can be extended to the separation of weak acids and bases with the addition of mobile phase modifiers and buffers to control ionization of the sample molecules.

This reference, which was compiled by W. Typical reversed phase stationary phases are hydrophobic and chemically bonded to the surface of a silica support particle Figure 1. Here, an additive is used to bind with the sample ion producing a neutral compound complex for separation.

Wed Sep 14, Tony Taylor and Crawford Scientific have several online courses and they usually conduct webcast and tutorials on various topics http: Check our website for new science and applications www. Williams, documents acid-base dissociation constants for more than organic and inorganic chemical compounds. The mobile phase is a liquid that moves through the packed bed of stationary phase in the column under pressure.
