Abstract
A process for producing a carbon sensor for measuring a composition, includes (a) providing first and second carbon electrodes each comprised of a bundle of linear, thin carbon members; (b) surrounding the first carbon electrode by dipping the first carbon electrode in a solution comprised of a reactive substance which reacts chemically with the composition to be measured; (c) disposing the first carbon electrode and the solution in a cylindrical ion permeable membrane to hold the solution in the first carbon electrode as well as between the first carbon electrode and the cylindrical ion permeable membrane; (d) positioning the cylindrical ion permeable membrane including the first carbon electrode and the solution in an insulating tubular member; and (e) disposing the second carbon electrode between the insulating tubular member and the cylindrical ion permeable membrane. Alternatively, the solution may be poured into a cylindrical ion permeable membrane and the first carbon electrode may be inserted into the cylindrical ion permeable membrane to hold the solution between the first carbon electrode and the ion permeable membrane and thereby surround the bundle.
