Nitrogen & protein determination in feed
A reliable and efficient method for the determination of total nitrogen and protein in feed, according to ISO 5983-2 and AOAC 2001.11, is presented. The samples are digested using Kjeldahl Tablets, hydrogen peroxide and the KjelDigester K-449. Distillation and boric acid titration are performed with the KjelMaster System K-375 / K-376 equipped with a colorimetric sensor.
