    Journal: Lab Delo; 1989; (4):25-7. PubMed ID: 2470959.
    Abstract:
    An express analyzer for urea measurements has been designed on the basis of the Exan-G glucose analyzer. The measurement bases on the potentiometric analysis of urease-immobilized urea hydrolysis. The detector consists of a flat pH electrode and an enzymic membrane. The sample volume is 50 microliters of whole blood, the measurement limit is 2-40 mM; 30 samples can be analyzed in an hour; the coefficient of variations is 3%. The optimal conditions of the measurements have been defined.
