Abstract: | A solid state Clselective microelectrode is describedand its performance in test solutions compared with that ofa microelectrode embodying a Clselective liquid ion-exchanger.The solid state microelectrode was found to be more selectiveto Cl against an interfering background of common inorganicion species than the ion-exchanger microelectrode. It performedsatisfactorily in the presence of NO3 and thus is suitablefor use with plant tissues. |
