The Mass Spectrometry Facility in the Department of Chemistry offers first-rate chemical analysis. Researchers use the facility for a variety of needs, from investigating the structure of key intermediates to obtaining publication quality spectra. Once students and postdoctoral researchers receive training on an instrument they may run their own samples on an as needed basis, with expert on-site assistance readily available. Senior spectroscopist, Dr. John Eng, handles samples submitted by researchers from outside the department.
All mass spectrometers are open for walk-up use 24-hours a day. Training for each instrument may be requested via a sign-up sheet next to the instrument or by contacting Dr. Eng and typically takes about 30 to 45 minutes. There are five mass spectrometers available in Room B14 of Frick Laboratories:
Agilent 6220 Accurate-Mass Time-of-Flight LC/MS: Using this high-resolution electrospray ionization mass spectrometer, synthetic chemists can routinely obtain accurate, sub ppm mass measurements for the complete characterization of their products for publication. The latest version of "Mass Hunter" software is available on this system.
Agilent 1100 and 1200 MSD Series Single Quadrupole LC/MS: These two instruments are configured for "walk-on" fast reverse phase liquid chromatography and direct injection analysis.
Agilent 5975C MSD for GC-MS Analysis: This reliable gas chromatography mass spectrometer vaporizes chemical samples and provides information about the mass of its components.
Agilent 7200 GC QTOF with 7890C GC: Provides high resolution GC-MS data and the attached 7890 GC is equipped with 2D GC column capabilities. It is part of Professor John T. Groves’ instrument cluster but researchers can make arrangements with the facility and the Groves lab to gain access to this machine.
