Our Mass Spectrometry Facility runs over 20,000 samples every year!!

       Our facility offers support for the analysis of a wide variety of analytes using mass spectrometry based techniques. We have instrumentation and expertise in multiple ionization techniques including ESI, APCI, APPI, EI, FI, and CI allowing for investigation of a wide range of molecular structures. With our four staff operated instruments, we provide services for molecular formula confirmation (accurate mass measurement), structural elucidation (MS/MS) and quantitation of small molecules. We also offer four user-run Walk-Up instruments that are available 24/7 for trained users.

          We are currently serving researchers from 10 departments at UT Austin, as well as users from 5 other UT campuses and 17 external universities / national labs! We would love to hear from you to discuss how we can help fulfill your sample analysis needs.
