To validate the formulas derived in the previous section, we have selected 15 compounds, which can be found in the supplementary material, Table . They were chosen first for having medium to high mobilities, to focus on those that can in principle suffer the highest distortions due to the transformation, as seen in section 2.2.2. In second place, by displaying good (i.e. relatively Gaussian) peak shapes in the electropherogram, to reduce as much as possible the variability in peak area stemming from peak integration, and again focus on the effects of the transformation. The compounds were prepared as a mixture of standards.
