摘要：Problem to be solved: to stably measure urea in sample water stably.

Pretreatment process for pretreatment of sample water by membrane apparatus havingreverse osmosis membrane andAnalysis of the urea concentration measured by analyzing

urea in the pretreated sample waterThe removal rate calculation process for

determining the urea removal rate in the membrane apparatus by measuring the amountof urea contained in the liquid after the liquid through the standard liquid of urea bypassing through the membrane apparatus andTo determine the concentration of urea bycorrecting the concentration measurement using the urea removal rate.It is preferable toperform the removal rate calculating step for each predetermined period.Diagram
