Spray drying of paracetamol with the Nano Spray Dryer B-90
Spray drying is a scalable, rapid and drying is a scalable, rapid, and economic technique that allows that converting liquids into dry powders. Paracetamol (also known drug for fever reduction and pain relief with anti-inflammatory effects. In this study, the feasibility of the Nano Spray Dryer B-90 to spray dry paracetamol in combination with Kollidon® 30, a widely applied 30, a widely applied excipient in the excipient in the pharmaceutical and cosmetic industry, was tested. The investigations focused on the influence on particle size, residual solvent content, and morphology.
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.
