LTQ XL™ Linear Ion Trap Mass Spectrometer
Obtain high sensitivity full scan MS along with in-depth MSn (CRM) capabilities with the Thermo Scientific™ LTQ XL™ linear ion trap mass spectrometer. A single quadrupole offers Selected Ion Monitoring. A triple quadrupole adds Selected Reaction Monitoring. A linear ion trap goes further by enabling Consecutive Reaction Monitoring where a selected ion is fragmented into a product ion and the resulting product ion further fragmented in additional consecutive steps. Each additional fragmentation step makes compound identification more certain and facilitates structural characterization.
The LTQ XL ion trap MS extends the legendary MSn performance of the LTQ ion trap, incorporating more techniques to generate structural information through innovations in Thermo Scientific ion trap technology.
Unparalleled sensitivity and unmatched MSn spectral quality
Pulsed Q dissociation (PQD) for generating more fragments and extending the low mass range
High-resolution isolation (HRI) enables isolation of isobaric mass peaks for cleaner MSn spectra
Ultra-fast polarity switching for high sensitivity analysis of unknowns
Automated data-dependent neutral loss for PTM and biotransformation analyses
Excellent charge state determinations with Ultra ZoomScan™
The LTQ XL supplies outstanding sensitivity and abundant structural information for:
Protein identification and quantitative differential expression analysis
Biomarker studies and PTM identification
Metabolite identification and quantification
High-speed LC methods
