PREDICTION OF THE EQUILIBRIUM VALUE OF A POTENTIOMETRIC SIGNAL - APPLICATION OF THE MEASURING TECHNIQUE TO MOLECULE-SENSITIVE SENSORS

A measuring technique suitable for the prediction of the electroanalyt ical equilibrium signal of a potentiometric sensor is described, based on the evaluation of asymptotes of the response of the cell and the c onfidence interval from the signals measured in the so-called informat ion dominant section of the response. The equilibrium voltage can be e valuated with great precision by comparing the calculated data with a predetermined threshold value. The technique was applied to the determ ination of the equilibrium signal of a carbon dioxide sensor.
