Trends and Challenges in Nitrosamine Testing: Part Two – Analytical Challenges
Sample preparation, limits of detection, and structural determination – our experts return for part two to discuss the main analytical challenges associated with nitrosamines
Detecting nitrosamines presents several analytical challenges, particularly in the pharmaceutical industry where ultra-low detection levels are often required. Techniques such as liquid chromatography coupled with mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) are commonly employed. However, issues like sample matrix interference, ionization suppression, and the differentiation between nitrosamines and isobaric compounds complicate analysis. Improved methods focus on ensuring chromatographic resolution and using isotopically labeled internal standards to enhance sensitivity and specificity.
