摘要 |
Method and device for measuring the concentration or urea or a similar substance, in a composite solution, particularly a dialysis solution, by catalytic decomposition of urea by urease. The differential conductivity of the reacted and unreacted solution is measured and is proportional to the urea concentration. A sample solution is taken out from the composite solution by a pump (6) and divided into two branches. The first branch passes a reactor column (10), a temperature equalizing coil (71) and a first measurement cell (7a), and the second branch passes a delay vessel (22), a temperature equalizing coil (72) and a second measurement cell (7b). <IMAGE> |
