✦ Synopsis

Retention of both porous and nonporous chromatographic silica gel supports of size range 0.62᎐10 m is investigated by gravitational field-flow fractionation with respect to sample preparation and carrier liquid composition. The possibility of sample mass calibration is demonstrated. The separation mechanism of particles in gravitational field-flow fractionation is discussed.
