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.
