STUDY OF FEASIBILITY OF Ag-AgCl ELECTRODE AS REFERENCE ELECTRODE FOR ISFET
用银-氯化银作ISFET参比电极的可行性研究

The preparation, principle and measured results of complex ion sensitive field effect transistor (ISFET) with Ag-AgCl reference electrode are described. Through theoretical analysis and experiments, the feasibility of Ag-AgCl reference electrode which does not contact with solution and the way of overcoming its unstability are put forward. It is explained that why the effect appearing in the ISFET does not conform to Nernst effect, when Na+, Ca++ cations etc. are measured with Ag-AgCl reference electrode.
