Contributions to reversed-phase column selectivity. II. Cation exchange (2011)
Journal Article

The contribution of cation exchange to solute retention for type-B alkylsilica columns (made from high-purity silica) has been examined in terms of the hydrophobic-subtraction (H-S) model of reversed-phase column selectivity. The relative importance... Read More about Contributions to reversed-phase column selectivity. II. Cation exchange.

Determination of catecholamines in urine using hydrophilic interaction chromatography with electrochemical detection (2011)
Journal Article

The determination of catecholamines in urine was investigated using hydrophilic interaction chromatography (HILIC) as an alternative to the commonly used reversed-phase (RP) method. A number of different approaches were explored, including per-aqueou...

Performance of silica monoliths for basic compounds. Silanol activity (2011)
Book Chapter

The large majority of pharmaceuticals, and in addition many compounds of biomedical significance, contain ionisable basic groups. This chapter considers the analysis of these important compounds on silica monolith columns.
