Abstract
The pore structures of four conventional stationary phases for reverse d-phase liquid chromatography have been studied and compared. Helium p ycnometry was used to determine the total porosity of the packing. Nit rogen sorptometry, inverse size-exclusion chromatography and mercury i ntrusion porosimetry have been applied to Kromasil, Vydac, YMC and Zor bax 10 mu m particles of C-18 chemically bonded silica. The agreement between the results derived from the three methods used for the determ ination of the volume pore size and the surface area distributions is excellent.
