  • Process and a measuring cell for the coulometric determination of the content of a component dissolved in water
    Patent number: 4211615
    Abstract: A process for the coulometric determination of the content of a component dissolved in water, e.g. oxygen gas in sea-water, and a coulometer cell for carrying out said process. The cell consists of an elongated, central measuring cell (1) and two auxiliary cells (2) which are directly connected to each end of the measuring cell (1). Electrolysis is performed simultaneously in the measuring cell (1) and the auxiliary cells (2) under such conditions that the concentration of the dissolved component will decrease at the same rate in all three cell elements.
