Scientists and analysts across all fields of testing and research are increasingly challenged by complex samples requiring advanced analytical selectivity. And where LC-MS/MS sensitivity alone is not enough to meet the demands of modern day quantitative performance, Differential Ion Mobility Spectrometry (DMS) has proven to be a valuable addition.
Break Through the Selectivity Barrier of Your LC/MS-MS SeparationsSCIEX offers the most innovative solution with its SelexION® DMS Technology. It is a small, planar mobility cell that is easy to install (in less than 2 minutes), easy-to-use and can significantly increase analytical separation power. No other ion mobility separation tool offers the reproducibility, robustness, and simplicity to deliver highly selective and sensitive quantitative and qualitative analyses, within a UHPLC time scale.
How does SelexION make this possible?The SelexION DMS technology separates ions based on differences in mobility in two different regions of the field dependent mobility curve. Due to its small size, the system can operate with very short ion residence times with optimal performance when using chemical modifiers. The DMS device can also be used in ‘transparent mode’ to allow for maximal workflow flexibility.
During an LC-MS/MS experiment, traditional fragmentation techniques like collision-induced dissociation (CID) have long been the gold standard. Electron-activated dissociation (EAD) is emerging as a transformative tool that enhances structural elucidation, particularly for complex or labile metabolites.
In the field of food chemistry and health, Prof. Nils Helge Schebb and his team at the University of Wuppertal are at the forefront of applying cutting-edge analytical methods to investigate how dietary components affect inflammation and chronic disease. Their work focuses on lipid mediators, particularly oxylipins, and how these molecules can be precisely measured and interpreted using liquid chromatography-tandem mass spectrometry (LC-MS).
Investing in a new liquid chromatography-mass spectrometry (LC-MS) system is a big decision, especially when your lab handles a wide variety of analytical tasks. With so many options out there, it’s easy to feel overwhelmed.
