WebbEffective Theoretical Plates (N eff) A measure of a column performance that accounts for the effects of unretained elution time, where t R’ is the adjusted retention time and is the standard deviation of the peak. This value also remains constant as retention gaps and guards are used.

WebbAssumptions. The McCabe-Thiele method is a very simplistic model of distillation and subject to the following assumptions: The mixture is binary i.e. there are only two components. The heat of vaporization of the two components are equal (When one mole of the heavier component is vaporised, one mole of the lighter component is condensed). WebbHow do you calculate theoretical plate? Column efficiency, indicated as the number of theoretical plates per column, is calculated as N = 5.54 (t R / w 0.5) 2 where t R is the …
