How Does the Roast Affect the Drink? Analysis of Coffee Using High Resolving Power and Accurate Mass

This webinar will utilize the Agilent 7250 GC/QToF and the Gerstel MPS to sample the headspace of ground coffee using solid phase micro extraction.

Green coffee beans were roasted to different final temperatures and compared to identify the aroma differences with high confidence using accurate mass, high resolving power, and accurate isotope ratios. The presentation will include the optimization of the sample introduction, GC, and MS to ensure a high confidence in the identification of the components that are found to be enhanced or reduced depending on the roast. MassHunter Qualitative Analysis tools, SureMass feature finding, library searching and accurate mass library creations will be discussed.

Presenter: Matt Curtis (GC/MS Applications Scientist, Agilent Technologies, Inc.)

Matt joined Agilent in 2013 as a GC/MS applications scientist in the Santa Clara, CA Center of Excellence, with GC/MS experience starting as an undergraduate. His primary responsibility is focused on providing instrument demos for customer interested in each technology Agilent offers; the GC/MS single quadrupole, triple quadrupole and the quadrupole Time-of-Flight. The variety of different applications submitted to the demo lab provide a unique knowledge of optimizing parameters for each experiment.
