Capillary Electrophoresis (CE) has become an accepted method for the separation of inorganic and organic ions. Usually, direct and indirect optical detection methods are used in conventional CE. However, with contactless conductivity detection, much better detection limits in the low ppb range are obtained compared to optical detection modes. Besides offering great flexibility in capillary handling, this detection technique can be performed on-capillary also with capillaries made of other materials than fused silica (PEEK^®, Teflon^®) and with capillaries having very small inner diameters.
