LTQ XL™ Linear Ion Trap Mass Spectrometer

The LTQ XL ion trap MS extends the legendary MS n 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
• Tissue imaging
• High-speed LC methods
