HILIC method optimisation using coined mobile phases

The thickness of the water layer depends on the chemistry of the HILIC column. I.e. a bare silica particle will have a different water adsorption compared to a diol column,and different from an amide column…etc. In addition to this,electrostatic and dipole-dipole interactions can occur when the analyte is partitioned on this water layer.
