The tube 2 may be Pb, Zn, Fe, Sb or Cd and may be coated with polyethylene, P. V. C. or polyamide 6. The internal structure may comprise one or more wire coils 5 about a central wire 4 or may comprise pieces of wire or crystals; suitable materials are Au, Pt, Ag, Cu and amalgams or alloys thereof. In use, an oxygen free KOH solution electrolyte is passed continuously through the cell, sample liquid being added continuously or intermittently as desired through an orifice 9. By adjusting the external resistance, measurements are possible over a wide range of concentrations from 10<SP>-7</SP>% to 100%. The internal electrode may be cleaned by temporarily loading it anodically with respect to a third electrode. The cell is particularly useful in measuring the concentration of cumol hydroperoxide during its production and further processing to phenol and acetone. Solvents may be added to the electrolyte to dissolve the sample liquid. Measurements may be made even if the sample liquid is immiscible with the electrolyte.
