Thermo Fisher LTQ Orbitrap Velos & LTQ Velos Mass Spectrometry

Product Information

The Thermo Scientific 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 confdence 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 isobaricallylabeled 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.

• Proven mass accuracy with ultra-high resolution
• Increased sensitivity for improved cycle time
• High efficiency in identifying proteins and isobaric species

• 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
• Dynamic Range: >5,000 within a single scan guaranteeing specified mass accuracy
• MS Scan Power: MSn, 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 efficiency of >15%
• Analog Inputs: One (1) analog input (0-1 V), One (1) analog (0-10 V)
