报道了串联压电式传感器在频率滴定中的应用，包括中和、沉淀、络合和氧化还原滴定。该方法基于串联的压电式传感器对溶液电导率的变化表现出灵敏和选择性的频率响应，可用于含有大量未反应外来电解质的样品溶液。
The applications of a series piezoelectric sensor for end-point determination in frequencimetric titrations, including neutralization, precipitation, complexation and redox titrations, are reported. The method is based on the fact that a series piezoelectric sensor shows a sensitive and selective frequency response to changes in conductivity of solution and can be applied to sample solutions containing large amounts of unreacted foreign electrolytes.
