Abstract

The paper presents selected results of an empirical study of transient responses of ion-selective potentiometric sensor to two classes of stimulus. First, voltage time-domain response of ion-selective structures was observed to changes of ion concentrations in the sample, flow speed and electric load of the sensor. Presented results explain essential accuracy/precision limitations of ion concentration estimates that can be obtained in practical applications for clean water. Second, current time sensor response to small voltage stimulus was observed for different ionic content of the sample. A behavioral model was built, that can be used (along traditional steady-state model) for Data Fusion-based enhancement of multiple-sensor measurements.
