LTQ XL

The LTQ offers legendary MSn performance, incorporating more techniques to generate structural information through innovations in ion trap technology.  The LTQ offers two dissociation techniques, CID and PQD.  Pulsed Q Collision Induced Dissociation (PQD) is a patented technique that eliminates the low mass cut-off concern inherent with all ion traps.  This results in extensive coverage for predicted and unpredicted metabolites, and the ability to perform peptide quantification using iTRAQ™ labels.
