A method of measuring the propensity to form calcium oxalate inlays of a continuous flow solution with a pH between 2 and 3 characterized by comprising measuring the rate of deposition of calcium oxalate inlays from dissolution on a Quartz crystal microbalance equipped with an upper face comprising a working electrode in contact with the solution and a second lower face isolated from the solution, in which the pH of the solution near the microbalance is electrochemically controlled between 3,5 and 9 and in which the working electrode is coated or made of one or more conductive materials selected from silver, lead, cadmium, thin-film electrodes similar to diamond with or without implanted ions, titanium silicides, niobium and tantalum, lead and selenium alloys, and mercury amalgams. |
