Mass Spectrometry Laboratory Gains New Instruments

Trevor Christenson, an undergraduate chemistry researcher, analyzes samples in the Department of Chemistry’s Mass Spectrometry Laboratory. The laboratory added three new instruments in 2015.

In 2015, the Mass Spectrometry Laboratory added three new instruments to its roster. They are a Thermo Fisher Scientific Q Exactive™ Plus funded by a grant from the National Institutes of Health, as well as a Bruker impact™ II and a Bruker microflex™ LRF. The Bruker instruments were funded by a generous bequest from former Professor Paul Bender and his wife, Margaret McLean Bender. The new instruments provide cutting-edge data that will help advance research in the department and across campus. The Q Exactive and the impact bring to the lab for the first time both accurate mass measurements of ions and fragments of ions (MSMS). 

As part of the Paul Bender Chemical Instrumentation Laboratories in the Department of Chemistry, the Mass Spectrometry Laboratory trains students in mass spectrometry techniques, provides students open access to most instruments in the laboratory, and processes samples for researchers across campus as a service. To date, 41 researchers have been trained on the new instruments. 

“These three new instruments bring the lab into this century as they replace two instruments acquired in the 1990s,” says Dr. Martha Vestling, Mass Spectrometry Laboratory director.
