What is Van Deemter Equation?

The mechanism of band broadening and how it can be linked to HETP was discussed in a 1956 paper entitled ‘Longitudinal diffusion and resistance to mass transfer as causes of nonideality in chromatography.As a result of this work, it was found that the relationship between a column’s efficiency and the mechanism behind band broadening could be described by an equation now known as the Van Deemter equation.

What is Chromatography?

A separation process based on the various partitioning coefficients of different solutes between the two phases.
Involving the interaction of solute(s) and two phases
Mobile phase: A gas or liquid that moves through the column.
Stationary phase: A solid or liquid that remains in place.
