We support FIU researchers and students with our expertise in mass spectrometry methodology and instrumentation. Our research facilities are also accessible to other academic, government and industry users through contract-based collaborations or service-for-fee.


We maintain state-of-the-art instrumentation enabling a broad range of analytical approaches. Our services range from small molecule synthetic identification to biological extract characterization to tissue imaging. Complex mixtures can be investigated using traditional chromatographic separations prior to mass analysis or they can be analyzed using the new high resolution FT-ICR instrument to obtain exact mass identifications.

We provide fee-for-service and contract-based collaborative research. For nonacademic users, this is an opportunity to have access to high-end mass spectrometry services without the need to invest in instruments. Collaborations in academic research usually involve the development of new mass spectrometry methods or techniques, leading to new breakthroughs. All inquiries regarding contract-based collaborations should be addressed to facility staff.

To submit a sample, fill out a Submission Form with as much information as you can and the Proteomics Addendum if appropriate. A principal investigator signature and account number are required for FIU users. For external users, a quote will be provided upon request.

Attach your sample to the submission form and leave the sample with the submission form in the inbox in CP 174 (or in the refrigerator/freezer for temperature-sensitive samples). If you are sending samples from outside the university, please contact us regarding proper procedures and handling.

Samples will be run in the order they are received, with priority given to samples from FIU researchers. Samples for each type of analysis will be run on the days specified by the schedule posted in CP 174. Samples must be received prior to the scheduled analysis time. For 9 a.m.-12 p.m. service times, the sample should be received before 9 a.m. For 1-4 p.m. service times, the sample should be received before 12 p.m. Samples submitted after these deadlines may not be run until the next scheduled analysis time.

Review our Sample Preparation Guidelines for more information.
