Development of an air gap urea specific electrode

, : Development of an air gap urea specific electrode. Journal of the Indian Institute of Science 66(9-10): 609-612

Air-gap urea-specific electrode has been developed from a combined pH electrode. Urease has been immobilized on polyacrylamide gel by the entrapment method. Urea concentration, pH, temperature, response time studies were conducted and found that optimum pH is 8.5 at temperature of in the two-minute response time. This electrode is also suitable for blood urea determination with five minutes response time giving reproducible readings.
