As the curves are describing the same chromatogram, by proportion, the ratio of the variance to the square of the retention, in the respective units in which the independent variables are defined, will all be equal.
Consequently,
where sv, sx and st are the standard deviations of the elution curves
when related to the volume flow of mobile
