A General Plate-Height Expression for Open Tubular Column Chromatography

Abstract

The plate-height behavior of open tubular columns, for both gases and liquids, has been studied fundamentally in the turbulent flow region. Appriate analytical expressions have been established on the basis of a purely phenomenological description of turbulent flow dynamics. It has been shown that under these flow conditions, the plate height decreases with increasing Reynolds number and that, most significantly, this decrease is strongly dependent on the mass distribution coefficient.
