Jan van Deemter


Jan Jozef van Deemter was a Dutch physicist and engineer known for the Van Deemter equation in chromatography.

Van Deemter equation

The van Deemter equation relates the resolving power of a chromatographic column to the various flow and kinetic parameters which cause peak broadening through
Where HETP is the height equivalent theoretical plate, A is the eddy-diffusion parameter, B is the longitudinal diffusion coefficient of the eluting material in the longitudinal direction, C is the resistance to mass transfer coefficient of the analyte between mobile and stationary phase, and u is the linear velocity of the column flow.
