Claims

[Scope of utility model registration request]

In a urea analyzer consisting of an immobilized urease membrane and an electrochemical detection section, the first
A dialysis section and a second dialysis section equipped with an ion-permeable immobilized urease membrane are arranged in series, and an electrochemical detection section is installed downstream on the second channel side opposite to the first channel through which the sample passes. A urea analyzer characterized in that the linear velocity ratio of the liquid supplied to the first flow path and the second flow path is 1:1.1 or more and 1:100 or less.
