He obtained his doctorate in physics from the University of Amsterdam in June of 1950. Starting in 1947 he began work for Royal Dutch Shell as a researcher and it was there that he developed and published his article in 1956.[4]
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.
