Nitrogen Determination in Reference Substances
Operational Quality Check
In order to verify the BUCHI Digest System K-437 or the Digest Automat K-438 in combination with the KjelMaster K-375 with KjelSampler K-376, the nitrogen content of different reference substances is determined according to the classical Kjeldahl method. All recoveries of the samples should be within the specification of 98-102%.
