The Thermo Scientic LTQ Orbitrap Velos combines the proven mass accuracy and ultra-high resolution of the Orbitrap mass analyzer, with the increased sensitivity and improved cycle time of the LTQ Velos. The high mass accuracy of the LTQ Orbitrap Velos increases the speed and condence of identication in complex samples by minimizing false positive identication. The ultra-high resolution provides certainty in analytical results by enabling molecular weight determination for intact proteins and in-depth analysis of isobaric species. The new HCD cell in the LTQ Orbitrap Velos is more efcient, resulting in improved quantitation of isobarically labeled peptides, such as applications requiring Tandem Mass Tags (TMT). Electron Transfer Dissociation (ETD) generates complementary information for highly sensitive PTM analyses and de novo sequencing.
Installation (IQ/OQ), training and service contracts available for additional cost.
Manufacture Specification
Mass Range- m/z 50-2000, m/z 200-4000
Resolution- 60,000 at m/z 400 at a scan rate of 1 Hz, minimum resolution 7,500 maximum resolution >100,000 at m/z 400
Mass Accuracy- < 3 ppm with external calibration, < 1 ppm using internal calibration
MS/MS- Electrospray Ionization (ESI)
Sensitivity- -2 L of a 50 fg/L solution of (Ion Trap) reserpine (100 femtograms total) injected at a ow of 500 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 165-615.**
Dynamic Range- >5,000 within a single scan guaranteeing specied mass accuracy
MS Scan Power- MS n , for n = 1 through 10
ETD option- 3 L/min infusion of a 1 pmol/L solution of Angiotensin I will produce an electron transfer dissociation fragmentation efciency of >15%
