Retention and Selectivity of Stationary Phases for Hydrophilic Interaction Chromatography

Journal of Chromatography A, 2011
More and more polar stationary phases have become available for the separation of small polar compounds in the past decade as hydrophilic interaction chromatography (HILIC) continues to find applications in new fields (e.g., metabolomics and proteomics). Bare silica phases remain popular, especially in the bio-analytical area.

Retention of β blockers on native titania stationary phase

Journal of Separation Science, 2011
AbstractIn recent years, metal oxides such as titania have been commercially available as chromatographic beds that can potentially be used to achieve novel separations of polar compounds. For example β blockers, which are more often encountered in environmental sciences, have a wide range of polarity, and their basic character leads to difficult ...

Retention mechanisms on metallic stationary phases

Journal of Chromatography A, 1989
Abstract An electron-rich, porous graphitic carbon stationary phase for high-performance liquid chromatography has been shown to act as an electron-pair acceptor of solutes under non-polar conditions. The application of delocalized electron bands as chromatographic substrates was extended to other conductors, namely a palladium metal stationary phase,

Retention characteristics of a new butylimidazolium-based stationary phase

Analytical and Bioanalytical Chemistry, 2005
A new HPLC stationary phase has been synthesized based on the ionic liquid n-butylimidazolium bromide. Imidazolium was covalently immobilized on a silica substrate through an n-alkyl tether and the retention characteristics of the resulting stationary phase were evaluated systematically.
