Analytical & Biological Mass Spectrometry Facility

The University of Arizona is home to a comprehensive suite of core facilities—the beating heart of cutting-edge research. Core facilities are state-of-the-art research hubs equipped with advanced instrumentation, expert personnel, and highly specialized services.

Providing access to essential tools and expertise across a diverse range of disciplines, core facilities are an invaluable resource for researchers across academia, government, and industry.

Our core facilities offer access to unique capabilities not available elsewhere on campus or even, in many cases, within the region. From advanced imaging and spectroscopy to high-throughput sequencing and computational resources, our facilities offer the support you need to realize the full potential of your research.

Whether you require technical assistance, experimental design guidance, or data analysis expertise, we’re here to support your project from inception to publication.

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. Mass measurements of whole proteins and polymers can be made using the Core’s Bruker Autoflex Speed MALDI-TOF. Routine analyses (low mass accuracy) of a variety of compounds are made using the Bruker AmaZon SL Ion Trap, the ABI Sciex 4000 Q-Trap and the Shimadzu GC-MS. Additional equipment in the Core includes a UV-HPLC with a fraction collector, an AKTA FPLC for protein separations, and 1D- and 2D-gel electrophoresis equipment.
