Pharmacy students Oda Kristine S. Rosseland, Ole Martin Drevland and Rolf Ståle Barstad participated in our course FRM2010 during autumn 2017. As part of this course, they conducted assays of ephedrine hydrochloride and lidocaine powders by titration according to the European Pharmacopoeia, to verify the purity of active pharmaceutical ingredient (API). Their titration curves are now published in our international textbook “Introduction to Pharmaceutical Analytical Chemistry” (Wiley, 2019, ISBN 978-1-119-36272-2). We used data from their laboratory reports as examples in the textbook (pages 378-379 and 382-383), on how to use titration for purity assay of APIs (including all the calculations). Oda Kristine is pictured just after receiving a copy of the book with her titration curve :)
