Trends and Challenges in Nitrosamine Testing: Part Three – Building a Method
Following part two, which explored the analytical challenges involved in nitrosamine testing, our experts return to offer their top tips for building a method from scratch
A methodical approach to building a nitrosamine analysis method is outlined, emphasizing the use of LC-MS and, where appropriate, GC-MS techniques. Analysts must identify suitable solvents and optimize mass spectrometry parameters for enhanced sensitivity. Key steps include preparing samples with nitrosamine impurities, optimizing chromatographic conditions, and ensuring adequate separation. Validation processes ensure reliability, supported by resources from the United States Pharmacopeia. Current technologies adequately quantify known nitrosamines, but unique challenges in formulating various drug products necessitate tailored approaches.
