摘要：A quartz crystal resonator is utilized to effect evaluation of viscoelastic natureof a film deposited on an electrode by electrochemical reaction. The quartz crystalresonator 1 is connected to a resonator characteristic measurement unit comprised of anoscillating circuit 2, a frequency counter 3, and an amplitude level meter 4. An

electrochemical measurement unit in the form of a potentiostat 7 is connected to aworking electrode given in the form of one of electrodes of the resonator 1, a referenceelectrode 5 and a counter electrode 6. These circuits 3, 4 and 7 are connected to a CPU 8.The resonator 1, reference electrode 5 and counter electrode 6 are dipped into anelectrolyte solution in an electrochemical cell 9. In another mode, the system utilizes aquartz crystal resonator precoated with a macromolecule sensitive film for analyzingdiffusion and viscosity variation in the film due to migration of electrochemically activesubstances relative to the film during the course of the electrochemical reaction.
