Abstract
Chiral stationary phases perform well when the underlying support for the chiral organic material is coated onto a silica pore widened by a hydrothermal treatment. The resulting silica is amorphous with a unimodal distribution of large pores. A variety of chiral stationary phases perform well and are distinguished, inter alia, by the treatment, if any, prior to coating the chiral organic material.
