A Coulometric Determination of Urea Nitrogen in Blood and Urine

[摘要] To determine urea nitrogen, ammonia resulting from urease hydrolysis of urea is titrated with coulometrically generated hypobromite ion using a direct amperometric end-point detection. In blood samples, the ammonia is first separated by the microdiffusion technic. The ammonia may be titrated directly in urine samples.
