N2 - In the present work a double ion sensor based on a laser scanned semiconductor transducer (LSST) for the simultaneous determination of K+- and Ca2+ -ions in solutions has been developed. Specially elaborated ion-sensitive membrane compositions based on valinomycin and calcium ionophore calcium bis[4-(1,1,3,3-tetramethylbutyl)phenyl] phosphate (t-HDOPP-Ca) were deposited as separate layers on a silanized surface of the Si/SiO2/Si3N4-transducer. The proposed multi-sensor exhibits theoretical sensitivities and the detection limits of the sensor were found to be 2 x 10-6 mol 1-1 for K+ and 5 x 10-6 mol 1-1 for Ca2+. The elaborated double sensor is proposed for the first time as a prototype of a new type of multi-sensor systems for chemical analysis.
