Abstract:
An electroanalytical cell comprising:a) a cell body housing, a reference electrode, a working electrode and a counter-electrode disposed at the lowermost portion of the working electrode;b) deoxygenation means for removing oxygen from a sample solution;c) means for feeding the sample solution to the deoxygenation means, means for feeding an inert gas stream to the deoxygenation means and means for causing the sample solution to flow as a stream in contact and equicurrent with the inert gas stream in the deoxygenation means;d) means for separating the sample solution from the inert gas stream and for removing the inert gas from the deoxygenation means after deoxygenation of the sample solution;e) an inlet for the deoxygenated sample solution provided in the cell body housing disposed in a space between the working electrode and the counter-electrode;f) an exit for the deoxygenated sample solution provided in the cell body housing disposed above the working electrode; andg) vacuum and or pressure means for causing the deoxygenated sample solution to flow to said exit and to be discharged therefrom, such that the space between the working electrode and the counter-electrode is constantly filled with the deoxygenated sample solution.
