The Thermo LTQ Velos Pro LC/MS delivers ultimate performance as the world’s fastest, most sensitive ion trap.

This optimized dual-cell linear ion trap mass spectrometer with high-pressure and low-pressure cells blurs the lines between traditional ion trap and triple quadrupole performance. A novel wide dynamic range discrete dynode detection system produces low RSDs and unprecedented quantitation from an ion trap. The Velos Pro broadens the MSn capabilities of the ion trap with a powerful new fragmentation technique, HCD (Higher-Energy Collisional Dissociation), with access to low mass fragments for complete structure characterization by tandem mass tag labeling.

Extremely powerful and flexible, the Velos Pro enables the identification and robust quantitation of even very low abundance compounds and provides absolute confidence in every result.

Applications include proteomics, metabolite identification, forensic analysis, clinical research and teaching.


  • S-lens technology and Generation II ion optics with novel neutral blocking technology for improved robustness
  • Discrete dynode Electron Multipliers with extended dynamic range.
  • Unique dual-pressure linear ion trap technology provides superior scan speed and resolution
  • Faster scanning and greater ion transmission improve identification of low-level analytes
  • Better resolution and higher scan rates
  • Scan function options include ZoomScan (high resolution) and Ultra ZoomScan (ultimate resolution)
  • Maximum ion trapping efficiency, higher ion isolation and fragmentation efficiency
  • Simultaneous identification and quantification of even complex samples increases throughput
  • Simultaneous identification and quantification of even complex samples increases throughput
  • Higher sensitivity for full scan MS and MSn analysis


  • Mass Range:
    • m/z 15 – 200
    • m/z 50 – 2000
    • m/z 200 – 4000
  • Resolution: 0.05 FWHM (full width half maximum) with Ultra ZoomScan
  • Scan Power: MSn, for n = 1 through 10
