Instrumentation Available

The Micromass QTOF2 Quadrupole/Time-of-Flight Tandem mass spectrometer is primarily used for full scan and tandem mass analysis of compounds of biological origin and their synthetic analogues including proteins, peptides, nucleic acids, natural products and metabolites. Electrospray ionization (ESI), nano-electrospray and atmospheric pressure chemical ionization (APCI) sources. A Waters 2695 HPLC system is available for online LC-MS and LC-MS/MS analyses. Alternately, an Agilent 1100 nano LC system may be coupled to the QTOF2 for peptide mapping and proteomics analyses.

Reserve time on the QTOF2

An HP 5970 GC/MS running in dedicated EI mode (mass range < m/z 550) is available for open access usage. The instrument is equipped with a J&W DB-5ms 30m GC column, with 0.25 mm ID and 0.25 µm film thickness.

waters gct

A Waters GCT Premier high resolution Time-of-flight mass spectrometer is primarily used for small organic analytes and low polarity materials. The instrument is equipped with electron ionization (EI), chemical ionization (CI), and field ionization/field desorption (FI/FD) ion sources. This instrument has a mass range up to m/z 800 in EI, CI, and FI modes and up to m/z 4000 in FD mode. Accurate mass measurement (<3 mDa) for elemental composition confirmation is available in EI, CI, and FI modes. The GCT Premier runs with an Agilent 7890 Gas Chromatograph with autosampler in "walk-up" access mode when not operated in solids probe mode by facility staff.
