Hybrid High Resolution MSn: LTQ FT Ultra
The LTQ FT Ultra combines the most advanced Ion Trap and Fourier Transform Ion Cyclotron Resonance technologies into a single instrument with unprecedented analytical power and versatility. Ultra-high resolution and sensitivity coupled with sub ppm mass accuracy, and MSn are universally available for the toughest applications demanding rigorous structural characterization.
The Ultra Cell - The Heart of the New FTICR
The Thermo Scientific LTQ FT Ultra mass spectrometer is the next generation hybrid FTICR featuring a novel ICR cell design, the Ultra Cell. This cell design produces enhanced sensitivity and greater dynamic range. The linear excitation characteristics of the cell allow larger cyclotron radii which significantly reduces space charge effects. These performance gains are achieved without the costs and difficulties associated with a higher field magnet.
The new LTQ FT Ultra is built on the proven Thermo Scientific linear ion trap and FTICR platform, featuring:
50 attomole on column On-line nano-LC-MS/MS of a 5 protein mix digest (50 attomole each on column, 30 min gradient). Data analysed with BioWorks 3.3. All proteins found with at least 2 peptides, high Xcorr and high peptide probability.
Maintain mass accuracy over a
Concentration independent mass accuracy in infusion or under LC conditions. Detect and correctly identify low abundant co-eluting species.
UNMATCHED MASS ACCURACY
Eliminates false positive identifications in bottom-up proteomics. Unambigous identification of unknown analytes with on-line LC-MS/MS at any concentration.
ULTRA HIGH RESOLUTION
Ultra high resolution available on demand with a single mouse click. Ultra high resolution is essential for the analysis of complex samples such as crude oil or Disolved Organic Matter (DOM).
