Abstract

Conductivity detection can be considered electrochemical technique as well but has the ability to detect any analyte irrespective of whether it contains an electroactive species or not. We used MEMS to fabricate the microelectrode. The Micro-channel was made by PDMS and modified by O2 plasma. In this study we detected organic components such as catechol, dopamine, histamine and vitamin C, and inorganic ions like K+, Li+ and Ca 2+. In 30 sec electrokinetic injection time for individual sample detection was performed using a field strength (E) of 440 V/cm, and E = 230 V/cm for separation electrophoresis. Each sample can be detected less than 90 sec excluding catechol.
