<p>A quartz crystal resonator is utilized to effect evaluation of viscoelastic nature of a film deposited on an electrode by electrochemical reaction. The quartz crystal resonator 1 is connected to a resonator characteristic measurement unit comprised of an oscillating 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 a working electrode given in the form of one of electrodes of the resonator 1, a reference electrode 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 an electrolyte solution in an electrochemical cell 9. In another mode, the system utilizes a quartz crystal resonator precoated with a macromolecule sensitive film for analyzing diffusion and viscosity variation in the film due to migration of electrochemically active substances relative to the film during the course of the electrochemical reaction. <IMAGE></p> |
