System peaks and non-linearity in capillary electrophoresis and high-performance liquid chromatography

Non-linearity and systems peaks are closely related. In fact, the occurrenc e of system peaks at positions that are not so easy to predict is the conse quence of non-linearity in the separation system. These things are observed in HPLC as well as in CE. In this presentation the theories and models dev eloped in both fields are compared. An attempt is made to formulate a commo n framework for the description of these phenomena in the two techniques, i ncluding affinity capillary electrophoresis (ACE).
