Abstract
Retention of both porous and nonporous chromatographic silica gel supp orts of size range 0.62-10 mu m is investigated by gravitational field -flow fractionation with respect to sample preparation and carrier liq uid composition. The possibility of sample mass calibration is demonst rated. The separation mechanism of particles in gravitational field-fl ow fractionation is discussed. (C) 1997 John Wiley & Sons, Inc.
