SpeedExtractor E-916, Multivapor, Hydrolysis Unit E-416, Extraction Unit E-816 SOX: Comparison of different extraction methods: Pressurized Solvent Extraction (PSE) using SpeedExtractor E-916 versus Weibull Stoldt method using Hydrolysis Unit E-416 and Extraction Unit E-816 SOX
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]. Therein, different titration techniques are specified.The Ph.Eur.describesback titration in the presence of the indicator methyl red mixed solution and the USP potentiometric boric acid titration.
