Abstract: THE PRESENT INVENTION PROVIDES THE USE OF NANOPOROUS PROTECTIVE MEMBRANE FOR CONTROLLING THE RATE OF TRANSPORT OF IONIC SPECIES IN THE ELECTRODE, CONTROLLING THE RATE OF LOSS OF SENSING MEMBRANE COMPONENTS, FOR MAINTAINING SUFFICIENT AND LINEAR RESPONSE SIGNAL FROM CHEMICAL SENSORS, AND TO ACHIEVE LOW AND CONSTANT DRIFT RATE OF CHEMICAL SENSORS. THE PRESENT INVENTION IS FOR USE IN THE SENSING ELECTRODE AND THE REFERENCE ELECTRODE SO THAT THE POTENTIOMETRIC SYSTEM IS SUITABLE FOR LONG TERM FIELD DEPLOYMENT.
