重点介绍了气体传感器的主要电化学原理。特别是，考虑电位、体积和边界电导传感器，重点考虑传输和速率系数相对于传感器信号的热力学和动力学的作用。大多数传感器原理都是针对氧化还原活性气体而设计和定制的。展示了如何构建类似的传感器原理来实现纯酸碱相互作用，从而能够适当检测酸碱活性气体，例如 NH3、CO2、H2O。 (C) 2000 Elsevier Science S.A. 保留所有权利。
Major electrochemical principles for gas sensors are highlighted. In particular, potentiometric, bulk and boundary conductometric sensors are considered with emphasis on the role of transport and rate coefficients with respect to thermodynamics and kinetics of the sensor signal. Most of the sensor principles are designed and tailored for redox-active gases. It is shown how analogous sensor principles can be constructed for pure acid-base interactions allowing an appropriate detection of acid-base-active gases, such as NH3, CO2, H2O.
