Abstract:
Studies on the structural and chromatographic properties of monolithic silica columns were reviewed. Monolithic silica columns prepared from tetraalkoxysilane by a sol-gel method showed high efficiency and high permeability on the basis of the small-sized silica skeletons, large-sized through-pores, and resulting through-pore size/skeleton size ratios much larger than those found in a particle-packed column.
