## Abstract Sedimentation Field‐Flow Fractionation (SFFF), which is a one‐phase chromatographic system, is shown to be a rapid and convenient method for the simultaneous determination of particle size and density in polydisperse colloidal samples. This can be done by a methodology based on the vari

## Abstract A study on the retention and separation of water‐soluble polymers and globular proteins by asymmetrical flow field‐flow fractionation (Asym. flow FFF) is presented. The applicability of only one carrier liquid to a great variety of samples with different charge stabilization and morphol
On page 122, Eq. (19) should read:
In this paper we demonstrate that the polydispersity p = M w / g N of narrow polymer fractions can be readily obtained by measuring band broadening and its velocity dependence in a thermal field-flow fractionation (thermal FFF) system. The thermal FFF method is shown to be more accurate than size ex
