<p>The proposed coulometric detector is of the "flow-past" type, in which the gas stream with the components to be measured is led past a surface which is covered with an electrolytic liquid. As reaction surface the outer surface of a porous layer is selected, which at the inner surface is in contact with a supply of electrolyte. To protect the detector against drying out, not the electrolyte, but the solvent, which is generally water, is supplied from a storage vessel. Stops are specified which allow the detector to take the form of a miniature measuring cell in mobile or stationary measuring stations for air pollution.</p> |
