N2 - The feasibility of using integrated injection moulded polymer electrodes as drive and detection electrodes for performing miniaturised isotachophoresis (ITP) separations with conductivity detection has been demonstrated. Injection moulded electrodes were produced from three different grades of carbon-filled polymer. Two of the electrode designs were found to be suitable for performing on-chip conductivity detection. The high-voltage characteristics of the microdevices were found to be suitable for performing ITP, with a power dissipation up to 1.4 W m−1 being achieved. Three model separations are presented to demonstrate the separation capability of the miniaturised injection moulded devices. Three anionic dyes, two inorganic anions and a mixture of eight alkaline earth, transition and lanthanide metal cations were analysed.
