Ion Max API source
The Velos Pro mass spectrometer is an optimized dual-cell linear ion trap with high-pressure and low-pressure cells that blurs the lines between traditional ion trap and triple quadrupole performance.
The first high-pressure cell enables maximum ion trapping efficiency, higher ion isolation and fragmentation efficiency. The second low-pressure cell, enables better resolution and higher scan rates. All of which, results in higher sensitivity for full scan MS and MSn analysis.
If you are in the market for an extremely powerful and flexible mass spectrometer, look no further than the Velos Pro dual-cell linear ion trap.
Applications include:
proteomics, metabolite identification, forensic analysis, clinical research and teaching.
A single quadrupole offers no more than Selected Ion Monitoring (SIM). A triple quadrupole adds Selected Reaction Monitoring (SRM) where a selected ion can be fragmented into a product ion. A linear ion trap goes further by enabling Consecutive Reaction Monitoring (CRM) where a selected ion is fragmented into a product ion and the resulting product ion further fragmented in additional consecutive steps (MSn). Each additional fragmentation step makes compound identification more certain and facilitates structural characterization.

System specifications
MS/MS sensitivity
Heated electrospray ionisation (HESI) 2 L of a 50 fg/L solution of reserpine (100 femtograms total)
injected at a flow of 400 L/min will produce a minimum signal-to-noise ratio of 100:1, for the transition of the
isolated protonated molecular ion at m/z 609 to the largest two product ions, m/z 397 and m/z 448, when
the mass spectrometer is operated at unit resolution in the full-scan MS/MS mode, scanning the product ion spectrum from m/z 165650.
Atmospheric pressure chemical ionization (APCI)
2 L of a 50 fg/L solution of reserpine (100 femtograms total) injected at a flow of 400 L/min will produce a minimum signal-to-noise ratio of 100:1, for the transition of the isolated protonated molecular ion at m/z 609 to the largest two product ions, 397 and 448, when the mass spectrometer is operated at unit resolution in the fullscan MS/MS mode, scanning the product ion spectrum from m/z 165650.
MSn sensitivity
Heated electrospray Ionization (HESI) A loop injection of 2 L of a 50 fg/L solution of reserpine (100 femtograms total sample) at a flow of 400 L/min will produce a minimum signal-to-noise ratio of 100:1, for the transition of the unit isolated protonated molecular ion at m/z 609 to the product ion at m/z 397 which is further fragmented to the product ion at m/z 365, when the mass spectrometer is operated at unit resolution in the full-scan MS/MS mode, scanning the product ion spectrum from m/z 165650.
