Keywords:
liquid chromatography, tube with a periodically varying cross-sectional area.
Abstract
The possibility of using a column with a periodically varying cross-sectional area in the liquid
chromatography is considered theoretically. Basic physical model of particle motion in the laminar flow of
the eluent in such a column is offered. Solutions of corresponding equation of motion are computed
numerically and are analyzed. It is shown that the effect of the chromatographic separation of components is
a result of differences in average velocities. The dependence of the spatial separation of the particles on the
basic parameters of the system is studied.
