Abstract
Solute band broadening in 50 mum I.D. open tubular columns coated with PS-264 stationary phase has been evaluated in supercritical fluid chr omatography. An improved method for on-column measurements of stationa ry phase swelling was used. For the conditions evaluated, a significan t contribution to the total solute band broadening originating from st ationary phase interactions was found. Possible sources of solute band broadening in the stationary phase are discussed.
