This course will teach state of the art chemical separations and methods which are coupled to mass spectroscopy for the modern analysis of pharmaceutical and biotechnology samples in industrial and academic laboratories. These include gas chromatography (GC, GC-MS), high performance liquid chromatography (HPLC, LC-MS), solid phase extraction (SPE and SPME), size exclusion/gel permeation (SEC, GPC), and ion exchange chromatography (IXC). Aspects of mass spectroscopy including ionization methods of electron impact (EI), chemical ionization (CI), positive and negative electrospray (ES+, ES-), APCI, and MALDI and techniques involving single and multiple ion/reaction methods (SIM, SRM, MRM) will be included. The separation and analysis of peptides, proteins and pharmaceuticals by LC and LC-MS will be a major focus. Isolation of drug metabolites from serum by SPE followed by HPLC analysis or using size exclusion chromatography to separate biomolecules, or labeling a peptide with a near infrared (NIR) dye are examples of important skills that are learned.
