The potentiometer is controlled by a microcomputer that allows individual, sequential multiplexed or random accesses to eight electrodes while employing only one reference electrode. The instrument was demonstrated by monitoring an array of seven flow\u2010through ion\u2010selective electrodes for Ag<jats:sup>+<\/jats:sup> and for three electrodes for Cl<jats:sup>-<\/jats:sup>, Ca<jats:sup>2+<\/jats:sup> and K<jats:sup>+<\/jats:sup>. The figures of merit of the individual and multiplexed (summed) readings of the electrode array were compared. The absolute standard deviation of the measurements made by summing the potential of two or more electrodes was maintained constant, thus improving the precision of the measurements. This result shows that an attempt to combine the signals of the electrodes to produce a more intense signal in the Hadamard strategy is feasible and accompanied by a proportional improvement in the precision of individual measurements. The preliminary tests suggest that the system can allow for 270 determinations per hour, with a linear range from 1.0 \u00d7 10<jats:sup>\u22122<\/jats:sup> to 1.0 \u00d7 10<jats:sup>\u22124<\/jats:sup> mol l<jats:sup>-1<\/jats:sup> for the three di\u00a1erent analytes. Detection limits were estimated as 3.1 \u00d7 10<jats:sup>\u22125<\/jats:sup> , 3.0 \u00d7 10<jats:sup>\u22126<\/jats:sup> and 1.0 \u00d7 10<jats:sup>\u22125<\/jats:sup> mol l<jats:sup>-1<\/jats:sup> for Cl<jats:sup>-<\/jats:sup>, Ca<jats:sup>2+<\/jats:sup> and K<jats:sup>+<\/jats:sup>, respectively.<\/jats:p>","DOI":"10.1155\/s1463924602000147","type":"journal-article","created":{"date-parts":[[2007,3,8]],"date-time":"2007-03-08T08:53:36Z","timestamp":1173344016000},"page":"105-110","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Design and development of a multichannel potentiometer for monitoring an electrode array and its application in flow analysis"],"prefix":"10.1155","volume":"24","author":[{"given":"Jarbas J.
