Nitrogen & protein determination in corn, flour and soy

KjelDigester K-449, KjelMaster K-375 with KjelSampler K-376: nitrogen and protein determination in corn, flour and soy according to the Kjeldahl method

An easy and reliable method for the determination of total nitrogen and protein in corn, flour and soy, according to ISO 20483:2006 and LFGB §64 L15.00-3, is introduced below. The samples are digested using the KjelDigester K-449. The distillation and boric acid titration are performed with the KjelMaster K-375 with KjelSampler K-376. The combination of the KjelDigester and the KjelMaster system K-375/K-376 increases the sample throughput.
