摘要

A thin-film platinum microelectrode has been produced using microfabrication techniques. This microelectrode behaves identically to the inlaid microdisk electrode. The fabricated thin-film microelectrode device is used for amperometric determination of CO₂ at room temperature. The microsensor shows a 90% response time of 30 s, a sensitivity of approximately 9 nA/% the reproducibility of the sensor is good for 6 h of continuous operation. However, these performance characteristic are affected by electrochemical crosstalk between the electrodes under long-tem operating conditions.
