© 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
Heaton, J. C., Wang, X., Barber, W. E., Buckenmaier, S. M., & McCalley, D. V. (2014). Practical observations on the performance of bare silica in hydrophilic interaction compared with C18 reversed-phase liquid chromatography. Journal of Chromatography A, 1328, 7-15. https://doi.org/10.1016/j.chroma.2013.12.058

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...
