Identification of Pharmaceutical Impurities by UPLC and a Fast Scanning Quadrupole MS

The escalating need for impurity analysis in pharmaceuticals provides the basis for evaluating fast, simple, and reliable methods of analysis. UPLC provides the speed and resolving power to develop rapid separation methods. A new breed of fast scanning quadrupole MS instruments are robust, reliable, easy-to-use, moderately priced, and well matched to the demand for measuring the narrow UPLC peaks in real-time but traditionally have not been considered as tools for reliable formula ID. By combining these systems with a new calibration available through MassWorks? CLIPS formula search, these systems can now become reliable workhorse systems for impurity determination.
