Deemter Curves in Ion Chromatography

Instead of the total plate height H and the linear flow velocity v, often the reduced plate height, h. 

The terms for the various contributions to the peak broadening combined in Eq. (2.24) give the impression that they are independent of each other. In practice, however, interdependence exists between these terms. This leads to a much smaller decrease in separation efficiency than predicted by simplifying the van Deemter theory. 

In this case, a compromise between separation efficiency and required analysis time has to be made. Flow rates between 2.0mL/min and 2.3mL/min have proved to be most suitable for practical applications.
