James Little - Mass Spec Interpretation Services

My name is James Little and my private consulting company is Mass Spec Interpretation Services. I contract for NIST, Wiley, and Sapec. Previously, I was a Research Fellow specializing in mass spectrometry at Eastman Chemical Company in Kingsport, TN and retired in early 2016 after >37 years of service. For 2017-2019, I did NMR as a limited service employee specializing in end group determinations for Eastman.

My main interest is the identification of organic compounds by mass spectrometry in organic mixtures. All the technical information on my web page was approved as technical session handouts, conference presentations, workshops, journal publications, courses, etc. for distribution outside Eastman. Other postings on this site are my own and do not necessarily represent Eastman’s positions, strategies or opinions. I also include a “little” information about my sailing experiences.

In 2017, I purchased a used Model S85 Tesla and starting to participate in electric vehicle events. In addition, I am a member of the choir at St. Paul’s Episcopal Church, play competitive duplicate bridge, and race sailboats on Watauga Lake.
