Isolation and characterization of impurities in pharmaceuticals

Separating and characterizing degradation products and impurity counts is important because it is not always possible to characterize unambiguously with commonly used scripting methods, which are often the first line of defense. These methods use detectors such as mass spectrometer, UV diode array detector, high performance liquid chromatography, capillary electrophoresis, etc. and many others are very useful and can reduce the time needed to characterize impurities.
