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.
Trifluoroacetic acid (TFA) is emerging as one of the most concerning ultrashort-chain PFAS in Europe’s food supply – particularly in cereals, a staple consumed daily by millions. A report from PAN Europe reveals a widespread and largely unmonitored contamination trend that raises serious questions about food safety, regulatory blind spots, and future monitoring strategies.
PFAS analysis is complex, but expert guidance doesn’t have to be. In this episode of our ‘Ask the PFAS expert series’, we’re joined by Michael Scherer, Application Lead for Food and Environmental, to answer the most pressing questions in PFAS analysis. From why LC-MS/MS systems are the gold standard for analyzing diverse PFAS compounds, to which EU methods deliver reliable results for drinking water, and to practical steps to prevent contamination, Michael shares actionable insights to help laboratories achieve accuracy, consistency, and confidence in their workflows.
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.
