In plateau theory, the HEPT deduced from the variance σ ² of the elution peak : $H = \frac{L}{N} = \frac{L σ^{2}}{t_{R}^{2}}$

can only be seen as a global measure of the influence of all the experimental parameters involved, but it doesn't allow us to specify the contribution of each parameter to the spreading of the peak as it progresses through the column. Spread depends on :
