Impact of GC Parameters on The Separation - Part 2: Choice of Column Internal Diameter
by Jaap de Zeeuw, Restek Corporation, Middelburg, The Netherlands.
In Part 1 of this series we focused on how to select the stationary phase, which is one of the seven important parameters we need to understand (see Figure 1). Once the most interesting stationary phase is selected, the column dimensions must be considered. Here column length, diameter and film thickness are the key parameters. In this article we turn our attention to the column internal diameter and its relevance.
