Mitigating matrix effects for LC-MS/MS quantification of nitrosamine impurities in rifampin and rifapentine

Since the discovery of potentially mutagenic nitrosamine impurities in pharmaceuticals in 2018, liquid chromatography-mass spectrometry (LC-MS) methods have been widely applied for the trace level quantification of nitrosamines. As more nitrosamines and drug samples are analyzed, method accuracy is...
