Orbitrap Elite -TFS- 2012

Installation date: February 2012


  • The Orbitrap Elite is a hybrid system composed with a linear ion trap (LTQ Velos Pro) and an Orbitrap cell. Thanks to its scan speed and sensitivity, the instrument allow the analysis of complex mixtures of proteins.
  • Connected with a nano-chromatography system using C18 column (75 µm x 50 cm) , from 2000 to 4000 proteins are identified in 2 hours runs.
  • The sequence information are obtained after CID, HCD or ETD fragmentation.
  • The instrument was acquired thanks to the financial support of the Fondation ARC pour la Recherche sur le Cancer and INSERM.

QTOF Xevo  –- Waters - 2015

Installation date: March 2015


  • The QTOF Xevo is equipped with a nanospray source and a standard ESI source. The chromatographic system (Acquity class M) is used for both nanoLC (C18 column, 75µm x 25 cm) and more conventional column (1 mm I.D.). The QTOF Xevo is used for the analysis of protein with LC-MS (C4 columns) and the quantification of peptides and little molecules


  • Resolution: 30000 (M/ΔM) in standard MS scan
  • -Accuracy: <10 ppm with external calibration
  • NanoLC MS sensitivity in the range of femtomole (peptide)
  • Scan speed from 0.1 to 1 second depending on sensitivity
