Sustainability in Analytical Chemistry Illustrated by Pharmaceutical Nitrosamine Testing

ELECTROPHORESIS, EarlyView.
ABSTRACT Following the valsartan scandal in 2018, the testing of drug substances and drug products for N‐nitrosamines has become a critical and mandatory quality control measure. The European Pharmacopoeia chapter 2.5.42 currently describes three analytical methods for this purpose: HPLC–MS/MS, GC–MS, and GC–MS/MS.
