The new MALDI source, available on the LTQ Orbitrap XL and Discovery, is ideally suited for proteomics and metabolism applications. Resolution of greater than 50,000 FWHM and mass accuracies of 2 ppm are available for MS, MS/MS and even MSn data.
Using the high resolving power and outstanding mass accuracy of the LTQ Orbitrap, researchers can now perform peptide and protein identification of MALDI-produced ions.
Other important applications include the high-throughput analysis of in-gel digests of 2D gel spots, de novo sequencing, iTRAQ™ quantitation, tissue imaging and small molecule analysis. more ...

The Thermo Scientific MALDI LTQ XL™ provides scientists with an MSn solution for analyzing whole tissue, biological and polymer samples without extensive sample preparation. A sensitive linear ion trap with MALDI capabilities provides faster sample preparation and complementary ionization to electrospray, allowing more reliable and definitive answers for protein identification and structural elucidation through MSn. more ...
Using the power of MSn and the sensitivity of the LTQ XL, compounds can now be detected, identified, and their distribution determined all in a single analysis saving time while increasing the level of knowledge of the biological system. It enables the acquisition and presentation of MS images directly from tissue samples. more ...
