Question

what useful information can be found from a van deemter plot in gas chromatography​

Answer 1

Answer:

Explanation:

• predicts that there is an optimum velocity at which there will be the minimum variance per unit column length and hence, a maximum efficiency.

• first application of rate theory to the chromatography elution process

Answer 2

Answer:

The van Deemter equation in chromatography, named for Jan van Deemter, relates the variance per unit length of a separation column to the linear mobile phase velocity by considering physical, kinetic, and thermodynamic properties of a separation.
