Introduced is a glass based planar sensor for the determination of redox potentials. The sensor was fabricated by applying and stoving an iron-containing paste on an alumina substrate partially covered with a platinum layer. Regarding the condition of the functional glass layer, it was characterized using several physical and chemical methods. Furthermore, the determination of redox potentials was carried out with different redox active substances. The results obtained with these electrodes were comparable to those...
