Detecting Contaminants in Complex Drug Samples

By optimizing chromatography and mass spectrometry methods, scientists overcome challenges in identifying contaminants such as N-nitrosamines.

In recent years, N-nitrosamines were found as contaminants in several drugs, leading to their recalls. This resulted in more stringent manufacturing requirements to detect contaminants in complex pharmaceutical samples using liquid chromatography and mass spectrometry (LC-MS). However, identifying trace amounts of contaminants is challenging. To overcome the technical difficulties of this task, scientists optimize their LC-MS methods and instrumentation to enhance sensitivity and specificity.
