Urease activity is determined by a combination of flow-injection analysis with optical sensor detection. Enzymatic hydrolysis of urea at pH 7.14 yields ammonium ions, which are determined using a fully reversible optical fibre ammonia sensor. Urea is contained in a buffered carrier stream into which
