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 m
## Abstract Extending our earlier measurements of homopolymer thermal diffusion, we characterize here the thermal diffusion of nine copolymers in toluene by thermal field‐flow fractionation (thermal FFF). The copolymers are organized into groups whose members differ in one major aspect only. These
