The Mass Spectrometry Facility (MSF) exists to provide top-quality mass spectrometry support to the faculty research groups of the Indiana University-Bloomington Chemistry Department. The MSF is one of many Technical Support Facilities in the Chemistry Department; its faculty advisor is Dr. David Clemmer. The laboratory is located in rooms A411 between Electronics Instrument Services and the Indiana University Molecular Structure Center and A702 in the Chemistry Building.

The facility is open Monday - Friday: 9:00 a.m. - 5:00 p.m. except for University staff holidays.

Announcements:

Two new (to us) LCT ESI-TOF mass spectrometers have been installed. These offer improved resolution and mass accuracy over the old API III. Check out the instrumentation page for a complete description. Training is currently available for these new instruments; check with Jon or Angie.

The Introduction to Organic Mass Spectrometry lectures given in Dr. Zach Aron's Organic Spectroscopy class are available here.

ALL SAMPLES MUST BE SUBMITTED WITH BOTH PAPER AND ONLINE FORMS.

Capabilities:

Walk-up electrospray ionization MS for both small molecules and biological samples
High resolution, high accuracy (±5 parts per million, ppm) mass spectrometry of small molecules by electron impact, chemical ionization, fast atom bombardment, and electrospray ionization
High mass resolution, high mass accuracy gas chromatographic mass spectrometry
Low mass resolution gas chromatographic mass spectrometry with both electron impact and chemical ionization sources.
Analysis of large biomolecules by time-of-flight or quadrupole mass spectrometry using either electrospray ionization or matrix-assisted laser desorption ionization
Capillary-scale (minimum column i.d. = 0.3 mm) liquid chromatographic mass spectrometry
Analysis of air and water sensitive compounds by electron impact, chemical ionization, fast atom bombardment, electrospray ionization, and matrix assisted laser desorption/ionization
Assistance in experimental design with respect to mass spectrometric analyses
