摘要
The invention is concerned with an electrochemical gas analyzer for determining the sulphur dioxide content of certain gases in particular, flue gases. The device comprises a measuring cell containing a measuring electrode for the determination of the depolarization current and further comprising an unpolarizable electrode in the same electrolyte. The gas input flow is utilized to cause a circulation of electrolyte containing the dissolved gas which moves in the space between the measuring and counter-electrode. The electrolyte is continuously renewed and the electrolyte leaving the cell is regeneratd and recycled. The sulphur dioxide dissolved in the electrolyte is removed outside the cell by treatment with air in the presence of activated charcoal.
