| Abstract: | A simple micro-capillary electrophoresis system to be used as disposable device was developed. A short commercial capillary was used as the separation channel, hydrostatic pressure generated by the sample employed for injection, and a voltage of 200 V used for separation in a 6 cm long capillary assisted by hydrostatic pressure of the carrier. The device was used for the separation of dopamine and catechol. Good reproducibility and efficiency was obtained. Because the instrumentation and operation conditions were simplified, and a replaceable modular separation channel was used, the proposed micro-capillary electrophoresis system is potentially useful in disposable devices. |
