Electropherogram of capillary zone electrophoresis with effective mobilityaxis as a transverse axis and its analytical utility - I. Transformation applying the hypothetical electroosmotic flow

For capillary zone electrophoresis, a new method of transformation from mig ration time to effective mobility was proposed, in which the mobility incre ase due to Joule heating and the relaxation effect of the potential gradien t were eliminated successfully. The precision of the mobility evaluated by the proposed transformation was discussed in relation to the analysis of ra re earth ions. By using the transformation, almost the same pherograms coul d be obtained even from the pherograms obtained originally at different app lied voltages.
