Working Principle

The LTQ XL extends the MSn performance of the LTQ linear ion trap with powerful new tools to generate extensive structural information for the most demanding proteomics and metabolism applications. With unparalleled sensitivity and ultra-fast cycle time, the LTQ XL delivers more information from less sample in less time. The unmatched high-quality spectra of the LTQ XL in combination with powerful new software packages deliver complete solutions for your structural elucidation questions.

The advanced XcaliburTM Data Dependent software suite, which includes the MS3 neutral loss experiment, enables rapid identification of post-translational modifications and metabolites. This feature greatly reduces the amount of time needed to analyze and interpret the data. Powerful software control and data processing in addition to innovative technology provide superior coverage for protein and metabolite analysis.


Specific Features of the Thermo LTQ XL

  •  Electron Transfer Dissociation (ETD) enabled.
  •   Multiple dissociation techniques including PQD.
  •   Extensive coverage for predicted and unpredicted metabolites.
  •   Fast polarity switching for high sensitivity analysis of unknowns.
  •   Intelligent Data DependentTM acquisition.
  •   Platform for hybrid MSn high resolution, accurate mass.
