Maximizing Throughput by Selecting the Optimum Column Lengths and Diameters.
Ken Broekhoven, Dierdrie Cabooter and Gert Desmet.
This article demonstrates how the throughput of a laboratory can be optimized by selecting the optimal particle diameter and column length for a given type of stationary phase. This selection can proceed via a step-by-step method, based on the recently established kinetic plot method for gradient separations. An example involving the separation of environmental pollutants is used to show how this approach works in practice.
