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.
Monitoring the Degumming Step of Crude Oils
The implementation of a BUCHI NIR-Online® process sensor after the degumming step provides full quality control of degummed oil. Within milli-seconds, different parameters such as phosphorus, moisure or free fatty acids, are continuously, simultaneously, and accurately measured with NIR.
