In the user interface the solvent in use for each channel can be selected in
order to get optimum flow and composition accuracy. Although selecting the
right solvent is not required for low ripple, especially for composition accuracy
across pressure it is vital for the compensation algorithm to use the right
solvent properties. The density of the solvents is increased under the
influence of pressure and a certain displaced solvent will expand again when
the pressure is released, for example across the column. In order to achieve
