The invention belongs to the branch of examination of electrochemical interphasic appearances, and can measure small changes in mass (from one nanogram) in a liquid environment. In order to simplify the procedures for the preparation, rejuvenation and measurement of surfaces of hydragyrum, the surface of metal electrode, which is insoluble in hydragyrum and is placed on piezoelectric plate, is prepared so that it is moistened by hydragyrum. It is rejuvenated by dripping hydragyrum on the surface of the electrode and pouring off the excess of it by turning the electrode at an angle of 90 degrees and bringing the measuring device to the primary position. |
