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.
- Attomole sensitivity
- Widest dynamic range ( > 4,000)
- ppb mass accuracy
- Resolution > 750,000
The new LTQ FT Ultra is built on the proven Thermo Scientific linear ion trap and FTICR platform, featuring:
- Automatic Gain Control – concentration independent ppb mass accuracy with space charge control
- Parrallel Acquisition – unmatched data dependant acquisition speed
- ECD and IRMPD – detailed characterization of peptides and proteins
- Fast Scan Rate with High Resolution – compatible with LC timescale
- Automated Optimization and Acquisition – simplified operation
