✦ Synopsis

Many chemical sensors exhibit exponentially decaying responses to a step change in the concentration. The determination of the time constant can greatly improve the specificity of the sensor. A spectroscopic method to determine the time-constant distribution is theoretically presented and its application to the analysis of the response to alcohol sensors is illustrated.

Models comprising, in sequence, linear analysers, C 1 ; y; C n ; non-linear transducer functions, and the Minkowski decision rule, are widely used to fit detection and discrimination data, especially when necessary to take into account the effect of probability summation. However, the analysers' cha
