The Analytical & Biological Mass Spectrometry Core Facility offers mass measurements of synthetic products, polymers and whole proteins. The Core is located in room 124J in the BIO5 Keating Bioresearch Building on the North Campus. Facility personnel determine the mass of the molecular components of a sample for structural confirmation and/or identification. Services include confirmation or determination of unknowns, Proteomics, and, in the future, Metabolomics and Lipidomics.
The Core is equipped with mass spectrometers that can measure molecular masses with high mass accuracy, including a Bruker 9.4 Tesla FT-ICR, a Thermo LTQ Orbitrap Velos, and a Thermo Q Exactive Plus Orbitrap. The latter two instruments are dedicated to peptide analysis. The Core also has a second Q Exactive Plus Orbitrap that will be dedicated to the analysis of lipids and metabolites. Routine analyses (low mass accuracy) of a variety of compounds are made using the Bruker AmaZon SL Ion Trap, the Thermo Altis and the Shimadzu GC-MS.
