Contributions to reversed-phase column selectivity. II. Cation exchange (2011)
Journal Article
McCalley, D. V., Marchand, D. H., Carr, P. W., McCalley, D. V., Neue, U. D., Dolan, J. W., & Snyder, L. R. (2011). Contributions to reversed-phase column selectivity. II. Cation exchange. Journal of Chromatography A, 1218(40), 7110-7129. https://doi.org/10.1016/j.chroma.2011.07.085

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
Kumar, A., Hart, J. P., & McCalley, D. V. (2011). Determination of catecholamines in urine using hydrophilic interaction chromatography with electrochemical detection. Journal of Chromatography A, 1218(25), 3854-3861. https://doi.org/10.1016/j.chroma.2011.04.034

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...

Some practical comparisons of the efficiency and overloading behaviour of sub-2μm porous and sub-3μm shell particles in reversed-phase liquid chromatography (2011)
Journal Article
Mccalley, D. V. (2011). Some practical comparisons of the efficiency and overloading behaviour of sub-2μm porous and sub-3μm shell particles in reversed-phase liquid chromatography. Journal of Chromatography A, 1218(20), 2887-2897. https://doi.org/10.1016/j.chroma.2011.02.068

At their optimum flow, sub-3 μm superficially porous or " shell" particles demonstrate similar efficiency to sub-2 μm totally porous particles. The performance of 0.21. cm i.d shell columns is however inferior to those of 0.46. cm i.d., presumably du...

Performance of silica monoliths for basic compounds. Silanol activity (2011)
Book Chapter
McCalley, D. V. (2011). Performance of silica monoliths for basic compounds. Silanol activity. In K. K. Unger, N. Tanaka, & E. Mactejevas (Eds.), Monolithic silicas in separation science, 173-188. Wiley VCH

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.
