-ethylene membrane; phosphorylated and crosslinked polyvinyl alcohol membrane, as working electrodes and a Ag/AgCl reference electrode. Developed electronic tongue is utilized for the sensing measurements of five different branded drinking water samples. Sensor characteristics, like, temporal stability, response stability, response patterns and repeatability of responses have been studied. Principal component analysis of the sensing data shows good discrimination among the analytes under study. Distinctive response patterns were observed for different drinking water samples in variation with the concentrations of dissolved minerals. Surprisingly sensor has done great job in order to monitor the dissolved minerals as present in tested samples with the help of standard calibrated sensing data.
