“From Electronic Cigarette Liquids to Sushi: Molecular Characterization Using Multiple Different Mass Spectrometers”

Frick Chemistry Laboratory, Princeton University

Lecture in Auditorium at 6:00 pm, followed by dinner in Atrium

Join us at our “Sushi & Snacks” pre-talk Mixer at 5:15 pm in the Atrium to network with colleagues!!



I am delighted to share with you the use of several analytical tools in my mass spectrometry toolbox to characterize a variety of consumer products.  Some of the products discussed are used by the general population spanning from high school students to senior citizens. 

Consumers are faced with a daunting task trying to decipher fact from fiction when purchasing products to improve health and longevity.  To assist consumers, we have been using several different types of mass spectrometers that include GC-TOF-MS, linear ion traps, Q-TOF, IMS-Q-TOF, and LDI-TOF-TOF to characterize all types of samples from electronic cigarette liquids to sushi.  Our philosophy for analyses centers around minimal or no-sample preparation and taking an untargeted approach in our workflows. This presentation will then focus on basic mass spectrometry that is used to determine purity, molecular structure, concentrations, and sources of a variety of consumer products that the audience uses daily. Also presented will be a forensic approach to solving an actual adulterated dietary supplement product sold as a health fraud product targeted towards senior citizens.


Professor Gene S. Hall received his BS degree in both Chemistry and Mathematics in 1973 from Tusculum College and his PhD in radiochemistry from the Virginia Polytechnical Institute (Virginia Tech) in 1978.  He then went on to the Department of Chemistry and Chemical Biology at Rutgers University in 1979 as an assistant professor of analytical chemistry to fulfill his life-long dream of

being a chemistry professor.  He is currently full professor where his focus is on using state-of-the-art mass spectrometry to characterize various consumer products such as dietary supplements, natural foods, artist paintings, and electronic cigarettes.


The meeting will be held in Frick Laboratory, Princeton University. The social mixer and dinner will be in the CaFe area of the atrium and the lecture in the auditorium (B02).  Frick Laboratory is located at the east end of the pedestrian bridge on Washington Rd. Visitor parking is available all day in Lot 21, corner of Faculty and Fitzrandolph Roads, or other lots along Ivy Lane after 5:00 pm. (see  Registration is required for this meeting. The seminar is free and open to the public.  Dinner is $25 ($10 for students) and $22.50 if prepaid with credit card (select "pay by debit or credit card").  To register and prepay go to our website at If you have questions, contact  Please make your dinner reservations by March 9, 2020.
