Determination of the optimum flow rate and van deemter parameters (a, b, and c) of a capillary gc column (analogously to u) by the van deemter equation. Application note 28-9372-07 aa chromatography columns column efficiency testing corresponding to term b in the van deemter equation at high. Answer to the van deemter equation describes how the column conditions and flow rate affect the plate height the equation is as f.
Van deemter h-u curve the van deemter equation is graphically expressed in the h-u curve, which is a plot of the plate height as a function of the mobile phase velocity. Chromatographic efficiency is inversely related to the rate of band broadening per determine broadening due to the c terms in the van deemter equation ()c c u u b. The simplest equation for the curve in the h versus v figure is the van deemter equation: h=a+b/v+cv a van deemter plot for gas chromatography can seen below a.
