液の循環と冷却タンクとして機能するのみである。Brazilian patent application No. PI 8008038 is an electrolytic cell consisting of one cell with two interconnected compartments containing an electrolyte, the sole purpose of which is to reduce the sample dissolution time. The cathode is placed in one compartment within which the sample is electrolyzed. Then, within this same compartment, the sample is connected to an electrolyte to form an anode, with one side of the sample immersed in the electrolyte. The other compartments only function as electrolyte circulation and cooling tanks.
