Abstract
Small pore silicas serving as the inert core support in chiral stationary phases show a surprising increase in column capacity relative to conventional chiral stationary phases having large pore silicas as the inert core support. This affords increased productivity and lower overall costs for chiral resolutions using a chiral stationary phase as adsorbent and an achiral liquid as eluant.
