Abstract

PURPOSE: An enzyme is made to act on creatinine in the sample and formed NH4 +, NH3 and the like are converted into NH3 gas, which is brought into contact through an ammonia-permeating membrane with an ammonia-absorbing solution and the resulting change in the electro-conductivity of the absorbing solution is detected to effect the indirect measurement of creatinine.
CONSTITUTION: A sample is introduced from inlet 21 and undergoes the action of immobilized creatinine deiminase 22, then is made alkaline by adding reagents from inlet 27. Thus, ammonia and ammonium ion resulting from the enzyme reaction are converted into ammonia gas and the gas comes in the second chamber 4, then flows out of the flow cell 1, finally is exhausted from outlet 23. The ammonia-absorbing solution is introduced from inlet 24 to react with the ammonia gas passing through the ammonia gas-permeating membrane 2. The change in the electro-conductivity of the absorbing solution is detected with electrodes 7, 7' to effect the indirect determination of the creatinine concentration in the sample.
