Ion-selective electrochemical sensor |
| abstract |
The ion concentration of a specific element in a solution may be determined by an ion-selective electrochemical sensor. Ionselective electrochemical sensors are produced from a non-oxide glass containing a doping element either having a reaction with, or of the same material as the ion concentration to be measured. The action of the ion concentration in the solution with the doping element in the non-oxide glass produces a potential which is a measure of ion concentration. Two techniques are employed to produce the non-oxide glass containing selected ions. One technique produces the composition by combining in one operation the high purity elements required for making a specific glass with the selected elemental material, and the second technique adds a dopant to a pre-treated glass speciman. With both techniques, a quartz ampule containing the glass and dopant is evacuated, sealed and heated. The heated glass and dopant form a molten mass which is agitated to insure complete mixing and then cooled to slightly above the softening point. Solidification of the finished material is accomplished by a quenching step to produce the desired characteristics. |
