Milk — Determination of urea content by continuous flow analyzer

Scope

This document specifies a flow analysis method with spectrometric detection for the determination of the urea content of milk in mass concentrations ranging from 0 mg/l to 800 mg/l, all in the undiluted sample. Other mass concentration ranges are possible, provided they cover exactly one decade of concentration (e.g. 100 mg/l to 1 000 mg/l). The range of application may be changed by varying the operating conditions.
