What it is

The Thermo Fisher Orbitrap Velos Pro is a hybrid mass spectrometer that combines a linear ion trap with an Orbitrap mass analyzer. The instrument belongs to the LTQ family of hybrid mass spectrometers.[1]

How it works

The Orbitrap Velos Pro hardware includes a dual-pressure linear ion trap, an Orbitrap mass analyzer, transfer optics, a C-Trap, and a collision cell for higher-energy collisional dissociation. The instrument supports CID, HCD, and optionally ETD fragmentation.[5][1]

Where it fits in the process flow

General reference — not yet source-verified

The Orbitrap Velos Pro sits in an analytical measurement workflow after sample preparation and ionization. The instrument receives ions from an external source and performs mass analysis on the resulting ion population.

Frequently asked questions

What is the mass range of the Orbitrap Velos Pro?

The mass range is m/z 50–2,000 and m/z 200–4,000.[5]

What resolution can the instrument achieve?

The resolution is 60,000 at m/z 400 at a scan rate of 1 Hz, with a minimum resolution of 7,500 and a maximum resolution greater than 100,000 at m/z 400.[5]

What mass accuracy does the Orbitrap Velos Pro provide?

Mass accuracy is less than 3 ppm RMS with external calibration and less than 1 ppm RMS using internal calibration.[5]

What is the sensitivity specification for MS/MS?

Using electrospray ionization, injection of 2 μL of a 50 fg/μL solution of reserpine (100 femtograms total) at 500 μL/min produces a minimum signal-to-noise ratio of 100:1 for the transition of m/z 609 to m/z 397 and m/z 448 when operating at unit resolution in full-scan MS/MS mode.[5]

What is the dynamic range of the instrument?

The dynamic range is greater than 5,000 within a single scan, guaranteeing specified mass accuracy.[5]

What fragmentation techniques are available?

The instrument supports CID, HCD, and optionally ETD. The HCD collision cell includes an axial field gradient for improved efficiency.[5]
