The Finnigan LTQ FT™ combines the most advanced Ion Trap and Fourier Transform Ion Cyclotron Resonance technologies
into a single instrument with unprecedented analytical power and versatility. For the first time, high resolution, accurate mass
determinations, and MSn are available for routine high-throughput analysis. This advanced, high performance mass spectrometer
is the right tool for metabolomic studies and all other applications demanding rigorous structural characterization.
   Robust accurate mass determination
   Mass accuracy of better than 2 ppm with external calibration
   Very high mass resolution for mixture analysis
   Maximum resolution of greater than 900,000 (FWHM)  
   Simultaneous high resolution, mass accuracy and sensitivity over one mass decade (e.g. m/z 200 - m/z 2,000)

   Fast data acquisition rate (1 second) with very high mass resolution (100,000 at m/z 400) for unprecedented LC/MS performance
LTQ FT is equipped with nano-ESI ion source providing soft ionization.
This may serve for elemental composition assignment, identification of unknowns and biomarkers.

 Instrument is shared with UCD Proteomics Core

MassWorks™

Revolutionary software for MS calibration and formula ID. Click here to learn more.

For high resolution mass spectrometers MassWorks dramatically improve ability to uniquely identify unknown formula from the long list of possible formula candidates obtained by mass accuracy alone, without the need for calibration standards! MassWorks software calibrates for spectral line-shape as well as for mass position allowing highly accurate comparisons between calibrated and theoretical spectra with Spectral Accuracy as great as 99.9%.
