Fractionation of a Three‐Particle Mixture by Brownian Sieving Hydrodynamic Chromatography

Size Fractionation by Slalom Chromatography and Hydrodynamic Chromatography

Hydrodynamic chromatography, also called separation by flow, is based on the use of the parabolic flow profile occurring in open capillaries or in the pores from a column filled with non-porous particles. The hydrodynamic chromatography separation medium, if any, is much simpler than that from size exclusion chromatography (porous particles), the former technique being used in the size-fraction...

Fractionation of human urine by gel chromatography.

High-resolution anion-exchange chromatography of human urine can resolve more than 150 constituents that absorb ultraviolet light. Prefractionation of urine on Sephadex G.10 helped us identify the constituents and simplified the anion-exchange chromatogram. The material associated with the 13 peaks obtained by gel chromatography was pooled and concentrated into six fractions, which were subsequ...

Hydrodynamic Chromatography

Table 1, which also includes relative molecular mass data obtained from sequencing the solutes. It is seen that fairly accurate values for relative molecular mass can be obtained for the larger molecules, which can be extremely useful when dealing with completely unknown biopolymers. The errors involved are signiRcantly greater for the materials of smaller relative molecular mass because the re...

Mass Fractionation in Hydrodynamic Escape

We show that mas s fractionation occurs during the course of hydrodynamic escape of gases f rom the a tmosphe re of an inner planet. Light gases escape more readily than heavy gases. The resul tant fract ionat ion as a funct ion of mas s yields a linear or concave downward plot in a graph of logari thm of remaining inventory against a tomic mass . An episode of hydrodynamic escape early in the ...
