The Department Mass Spectrometry facility has added a new Bruker rapifleX MALDI-TOF-TOF mass spectrometer to its suite of instruments. The rapifleX purchase was made possible through an NSF MRI grant written by Dr. Carolyn Cassady. The new mass spectrometer provides state-of-the-art capability for mass analyzing non-volatile samples, such as proteins and polymeric materials. The instrument also brings chemical imaging capability to the facility allowing spatially resolved analysis of the chemical composition of materials. For information on using the new rapifleX MALDI-TOF-TOF, please contact Dr. Qiaoli Liang, Mass Spectrometry Facility Manager.
