title: [A NH(+4)-selective-enzymatic flow-through system. A method for the continuous enzymatic, electrochemical determination of urea, II (author's transl)].
abstract: A flow-through system for the measurement of urea concentrations is described, using soluble urease and consecutive determination of liberated ammonium ions by a selective disc-electrode. The active component of the electrode membrane was the carrier-antibiotic nonactin which was incorporated in a polyvinylchloride matrix.
