    Description / Table of Contents: Zusammenfassung Harnstoff-sensitive Enzymelektroden mit Spitzendurchmessern zwischen 50 und 500μm wurden durch Immobilisierung des Enzyms Urease auf der Spitze einer Antimon-Elektrode hergestellt. Diese Elektroden verhielten sich linear im Konzentrationsbereich 1,0×10−4−1,0×10−2 M, und hatten eine Steigerung von 40–45 mV pro Dekade der Konzentrationsänderung. Die Antwortzeit dieser Elektroden liegt unter 1 min und die Auswaschzeit beträgt l–2 min. Diese Art Elektroden hat eine Lebensdauer von mehr als 3 Monaten.
    Notes: Summary Miniature enzyme electrodes sensitive to urea have been made with tip diameters ranging from 50 to 500μm by immobilizing the enzyme urease on the tip of an antimony electrode. These electrodes give a linear response in the concentration range of 1.0×10−4-1.0×10−2 M urea with a slope of 40–45 mV per decade change in concentration. The response time of these electrodes is less than 1 min and the wash time is 1–2 min. This type of electrode has a minimum life time of 3 months.
