一种利用离子交换膜研制的电化学氧传感器

A New Type of Ion-Exchange Membrance Based Electrochemical Oxygen Sensor

利用聚苯乙烯阴离子交换膜研制的金为催化剂，采用碱性体系的新型控制电位电解型氧传感器，克服了以往电化学氧传感器的缺点，具有响应时间快、稳定性好、噪声低、本底电流小、温度系数低等优点。

The characteristics of electrochemical oxygen sensor with ion exchange membrane polystyrene was evaluated. The sensor exhibits fast response, low residual current and noise, small temperature coefficient and long-term stability.
