"It is a robust instrument with good quality. The software interface is easy to use and user friendly. The accuracy and resolution may not be as good as other instruments, such as the Orbitrap."

"LTQ XL is a good ion trap for neuropeptide analyses, and it's fairly easy to maintain. Changing ion source to new objective source improves capillary-LC interface. However, I feel it should scan faster."

"The hardware is of top-notch construction and analytical performance, however the software could be a bit more user friendly."
The LTQ XL™ extends the legendary MSn performance of the LTQ™, incorporating more techniques to generate structural information through Thermo Scientific’s innovations in ion trap technology. Thermo Scientific's LTQ XL is the only mass spectrometer that offers multiple dissociation techniques, PQD, ETD and CID. 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.
In addition, fast polarity switching for high-sensitivity analysis of unknowns, high resolution isolation (HRI), intelligent Data Dependent™ acquisition, and optional high resolution accurate mass functionality are all tools to help the researcher gain confident structural identification routinely.
