DESI QiT MS
DESI imaging station in Fenandez Lab. Motion is controled by a computer controled (x,y) stage. This setup is coupled to a Quadrupolar Ion Trap, specifically the LCQ Deca XP Plus.
DESI DMS-TOF MS
DESI imaging station in Fenandez Lab. Motion is controled by a computer controled (x,y) stage. This setup is coupled to an AccuTOF mass spectrometer modified to accomodate a DMS filtering cell (not shown).
DESI TWIMS-TOF MS
Our Center also has the capability of performing DESI MSI experiments coupled to our Synapt G2 mass spectrometer. This instrument purchased through the Center for Chemical Evolution (CCE).
LA-Plasma Q-TOF MS
Our Center also has the capability of performing laser ablation plasma MSI experiments our Bruker micrOTOFQ II mass spectrometer. This instrument purchased through an NSF MRI instrument development grant.
Computer Cluster
Our center is heavily involved in developing better visualization tools and data processing algorithms for large Imaging mass spectrometry datasets.

Multispectral imaging technologies capture spatial as well as spectral information from a sample. For example, quantum dots target specific biomarkers and emit different fluorescent spectra; or, mass spectrometry reveals different molecular distributions within a sample. OmniSpect untangles the contributions from different sources within a sample by leveraging their known spectral profiles or inferring them directly from the data.
