Abstract: PURPOSE:To improve detection sensitivity by shorting a working electrode to a reference electrode and measuring the change in potential by the chemical reaction of this working electrode as a change in the potential of the working electrode with respect to the potential of the gate film of an ISFET which is a reference. CONSTITUTION:The working electrode 2 is connected to the liquid junction type reference electrode 6 of an Ag-AgCl type or calomel type in potentiometry to investigate the chemical reaction in a buffer soln. by investigating the change in the potential of the electrode 2 with the gate film of the ISFET 1 as the reference electrode.
