Using ALL of the Information from GC-HRMS to Identify Small Differences Between Similar Samples

Event Overview:

Analysis of complex mixtures with gas chromatography coupled with high-resolution time-of-flight mass spectrometry (GC-HRTOF-MS) can produce a large amount of data, and database search alone is. A new software program is developed for a new GC-HRMS system that combines all of the available information from database search, molecular formula determination, and retention index matching with statistical analysis. Small differences between two similar Scotch whisky samples are identified to illustrate the analytical workflow.

Key Learning Objectives:

• Learn about a new GC-HRMS system with new software for data analysis of complex mixtures
• Learn how integration of ALL of the information from GC-HRMS simplifies and facilitates analysis
• Learn how statistical analysis of GC-HRMS data from two very similar samples identifies small differences

Who Should Attend:

• Lab Managers
• Analytical Chemists
• Researchers

Speakers

Dr. Robert (Chip) Cody
Principal Scientist
JEOL USA, Inc.

Robert B. (Chip) Cody received his B.S. in Chemistry from Roanoke College in 1976 and his Ph.D. in Analytical Chemistry from Purdue University in 1982 with the late Professor Ben Freiser. From 1982 to 1989 Dr. Cody worked at Nicolet Analytical Instruments (Madison, WI) in the Fourier Transform Mass Spectrometry group as Senior Scientist, Nicolet Fellow, and University of Wisconsin Fellow. He has worked at JEOL USA, Inc. in Peabody, MA for the past 32 years and is currently a Principal Scientist.

Dr. Cody is responsible for developing the trapped-ion tandem-in-time MS/MS and MSn techniques, laser-desorption in a trapped ion mass spectrometer, and Electron Impact Excitation of Ions from Organics (EIEIO) and is the coinventor of the DART ion source. Current research involves applications of ambient ionization (including DART, PaperSpray and inlet ionization) and new strategies for data interpretation. He has consulted with NASA on the Mars 2020 Rover project, served as Vice-President for Arrangements for the American Society of Mass Spectrometry, and was awarded the 2011 Anachem Award and a 2012 Purdue University Distinguished Alumni Award. In addition to numerous publications, patents and book chapters, he is co-editor (with Marek Domin of Boston College) of the book Ambient Ionization Mass Spectrometry and is author of the Mass Mountaineer software suite and two scientific apps for the iPhone.
