Potential-time curves of six sensors were obtained by measuring the respective emf values in six different concentrated DB solutions (each 10.0 mM) all undergoing successive dilutions in which repeated removal of an aliquot of the respective sample and addition of equivalent volumes of BRB solutions (pH = 7.0). The nearly superimposed profiles of the six different screen-printed sensors highlight the reproducibility of the sensors.
