Capillary electrophoresis is often plagued by unstable and unrepeatable results. In this paper, some novel modes are derived theoretically and illustrated by separation examples, as expected these modes can resist the change of some conditions under certain prerequisites and obtain super stable electropherograms. They are weighted mobility spectrometry, migrated charge spectrometry, charge density spectrometry, molar charge density spectrometry, diffusion coefficient spectrometry, liquid-phase mass spectrometry, and their ratio spectrometry. The first four are real-time measurement modes while the others are post-experimental modes. These modes need to develop new devices and algorithm, but they are all highly promising and worth of further exploitation.
