This MALDI TOF can be used for the analysis of a broad range of compounds including small molecules, peptides, proteins, nucleic acids, and synthetic polymers. The Microflex accepts 96 spot target plates. The matrix assisted laser desorption ionization (MALDI) source operates with a 60 Hz nitrogen laser at 337 nm. The instrument has a mass range of up to 20,000 m/z in reflectron mode or 500,000 m/z in linear mode. Additionally the instrument is capable of mass spectral imaging. Polytools software is available for the analysis of polymer data.

The MALDI TOF is made available to BioPACIFIC MIP users through the DCB Mass Spectrometry Facility at the Department of Chemistry and Biochemistry at UC Santa Barbara.
