Electronic tongue is a device which is used to classify different taste by multi-sensor. In this work, we had measured the production of chemical composition of five different mineral water by four kinds of selected ion array (sensitive to H+, Na+, Ca2+ and K+, respectively). Principal component analysis, a kind of multivariate data analysis was used to educing of total number of the sensors in the...
An electronic tongue system to automatically detect heavy metal in sea water Hg, Fe, Cr elements is develop. The detection units of electronic tongue are based on three light-addressable potentiometric sensors (three-LAPS). All-solid-state mercury ion-selective electrodes (Hg-ISE), Fe-ISE and Cr-ISE, are also respectively as targets of pulsed laser deposition (PLD) technique and are prepared to three...
