ABSTRACT:
Sedimentation field flow fractionation apparatus having a rotor-mounted fractionation column, has detectors positioned to observe the fluids from the column while still in the rotor. Designs include parallel reference and fractionation columns having their outflows compared in a rotor-mounted fluid flow density balance. Optionally weired channel columns provide a free fluid surface for more efficient resolution. Horizontal rotational axes are preferred. Rotor-mounted fluid flow density balances are also provided which are suitable for detecting liquid density changes in the other applications, such as liquid chromatography.
