Evaluation of additives on reversed-phase chromatography of monoclonal antibodies using a 1000 Å stationary phase (2019)
Journal Article

© 2019 Elsevier B.V. A wide pore (1000 Å) diphenyl stationary phase was evaluated for the analysis of monoclonal antibodies (mAbs), comparing a conventional mobile phase of acetonitrile-water containing overall 0.1% trifluoracetic acid (TFA) with a s...

Study of retention and peak shape in hydrophilic interaction chromatography over a wide pH range (2015)
Journal Article

© 2015 Elsevier B.V. Retention factor and column efficiency measurements were made for 14 test compounds comprising acids, bases and neutrals on two pairs of amide and bare silica HILIC columns, each pair obtained from a different manufacturer. The c... Read More about Study of retention and peak shape in hydrophilic interaction chromatography over a wide pH range.

Practical observations on the performance of bare silica in hydrophilic interaction compared with C18 reversed-phase liquid chromatography (2013)
Journal Article

The kinetic performance of a bare silica and C18 phase prepared from the same sub-2. μm and 3.5. μm base materials were compared in the HILIC and RP mode using both charged and neutral solutes. The HILIC column was characterised using the neutral sol...

Influence of phase type and solute structure on changes in retention with pressure in reversed-phase high performance liquid chromatography (2013)
Journal Article

The influence of pressure on the retention of several types of solute, including acids, bases and neutrals, was studied by the use of restriction capillaries added to the end of various monomeric and polymeric octadecylsilyl-modified 5. μm particle s...

Comparison of an organic polymeric column and a silica-based reversed-phase for the analysis of basic peptides by high-performance liquid chromatography (2005)
Presentation / Conference Contribution

The performance of a purely polymeric and a Type B silica-based C 18 reversed-phase column was compared for the analysis of the basic peptide bradykinin and some analogues in order to assess the contribution of silanol interactions to peak shape. Goo... Read More about Comparison of an organic polymeric column and a silica-based reversed-phase for the analysis of basic peptides by high-performance liquid chromatography.
