A micro-extraction unit was inserted into the CE system sampling device and ensured excellent sample clean-up and injections directly from the membrane surface. Transient isotachophoresis (t-ITP) combined with large electrokinetic injections of selectively extracted basic analytes increased the sensitivity of the analytical method up to 300-fold when compared with conventional hydrodynamic injections and capillary zone electrophoresis (CZE) of the basic analytes.
