E17-02: LC/MS: Theory, Instruments and Applications

Two-Day Course 
Sunday, Nov. 12 – Monday, Nov. 13; 8:30am – 5:00pm
Dr. Guodong Chen, Bristol-Myers Squibb, Princeton, NJ 
Dr. Ragu Ramanathan, Pfizer, Groton, CT 

COURSE DESCRIPTION
This two-day course is designed to be an introduction to the theory and practical implementation of LC/MS and LC/MS/MS technology in the laboratory. It emphasizes problem-solving skills with examples encountered in industrial and academic research including characterization of trace level drug substance impurities and degradation products, identification of drug metabolites, and the analysis of natural products and bio-molecules. The interpretation of mass spectra will be illustrated with practical examples. In addition, structure determination of proteins and peptides will be presented, including antibody-drug conjugates. This course will focus on atmospheric pressure ionization interfaces including electrospray and atmospheric pressure chemical ionization, and will survey the various mass analyzer options. This course will address issues regarding the coupling of capillary HPLC, microbore HPLC, UHPLC and standard 4.6 mm chromatography. A thorough coverage of approaches toward method development for both qualitative and quantitative analysis of pharmaceutical products and biomolecules will provide a good starting point for understanding the practical issues facing implementation of LC/MS in the laboratory. Furthermore, an overview of the current state-of-the-art of automating the LC/MS laboratory including the interfacing of automated sample preparation devices will be provided. Finally, this course will cover analytical method development in protein mass spectrometry combined with separation techniques for analyzing proteins and peptides.
