MultiDist and BasicDist with BUCHI SO2 glass set: Determination of total sulfur dioxide in dried apricot mousse as a reference sample, bio-apricots & a reference standard sodium metabisulfite by the patented BUCHI Method with iodometric titration.
Nitrogen and Protein Determination in Animal Feed according to the Kjeldahl method
The determination of protein in feed is a routine procedure for quality assurance and labelling. A simple and fast method for protein determination in feed products according to the ISO 5983-2:2009 and AOAC 954.01 regulations is introduced below. The sample is digested with sulfuric acid and Kjeldahl Tablets Titanium using the digest Automat K-438, followed by distillation and titration with the KjelMaster K-375 with KjelSampler K-376.
Nitrogen Determination in Pharmaceutical Active Peptides
Nitrogen and total protein determination in pharmaceutical products are described in the European Pharmacopoeia (Ph.Eur.) section2.5.9 and 2.5.33 method 7 [1, 2]. In the Pharmacopoeia of the United States (USP), nitrogen determination is described in section461 [3].
