The Facility provides mass spectrometry service in support of analyte identification/verification, structural elucidation, and quantitation of individual compounds and complex mixtures for the University of Missouri and outside users (please see our Services and Fees). In addition to service work, we are available for collaborative projects and are conducting research in the fields of gas phase ion chemistry and surface chemistry.

Work in the Mass Spectrometry Facility centers around our Finnigan TSQ7000 triple-quadrupole mass spectrometer. This instrument is equipped with electrospray (ESI) and atmospheric pressure chemical ionization (APCI) sources which can operate in positive and negative ion modes. Samples can be introduced by direct infusion or following separation using high performance liquid chromatography. Both qualitative and quantitative analyses are available by using full scan, single ion or selected reaction monitoring. A variety of tandem mass spectrometry experiments can be performed with ions produced by ESI or APCI methods.

In cooperation with the MU Proteomics Center, other mass spec services may be available, including MALDI-TOF and TOF-TOF analyses.

Current and future users should note: before planning use of the facility for research, analyses, or before applying for grants, please consult with us about your requirements and time needs. This will permit us to best match your goals with available methods.
