Overview of Services

The IU Mass Spectrometry Facility has been confirming atomic composition by accurate mass spectrometry since 1965.  It offers self-serve nominal mass GC-MS and LC-MS as well as staff-supported advanced experiment design/execution.  We are found on the 4th floor of the Chemistry Building at IU-Bloomington.  Services include walk-up GC-MS, walk-up LC-MS, headspace GC-MS, accurate MS formula confirmation by ESI, APCI, EI, screening by high throughput LC-MS, MALDI-TOF MS of polymers, MALDI Imaging, LC-MS or GC-MS method development, GC-MS metabolomics, triple quad LC-MS-MS, and training for most of the above techniques.  We also work closely with Dr. Jonathan Trinidad and the staff of the Laboratory for Biological Mass Spectrometry in Simon Hall.
