Factors Affecting Mixed-Mode Retention Properties of Cation-Exchange Stationary Phases

Journal of Chromatography A, 2023
Cation-exchange stationary phases were characterized in different chromatographic modes (HILIC, RPLC, IC) and applied to the separation of non-charged hydrophobic and hydrophilic analytes. The set of columns under investigation included both commercially available cation-exchangers and self-prepared PS/DVB-based columns, the latter consisting of ...

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,
