| titleOfInvention | Urea quantification method and analyzer |
| abstract | PROBLEM TO BE SOLVED: To enable stable and accurate quantification of urea in a sample water. SOLUTION: A pretreatment step of pretreating sample water with a membrane device having a back-penetrating membrane, an analysis step of analyzing urea in the pretreated sample water to obtain a measured value of urea concentration, and a standard solution of urea. The removal rate calculation step to obtain the urea removal rate in the membrane device by measuring the amount of urea contained in the liquid after passing the liquid through the membrane device, and correcting the concentration measurement value using the urea removal rate. A step of obtaining a quantitative value of urea and a step of obtaining it are carried out. It is preferable to carry out the removal rate calculation step at predetermined intervals.
