Mass spectrometry can provide exceptional sensitivity, selectivity, resolution, throughput, and mass accuracy, but certain applications demand additional levels of selectivity. This is where differential ion mobility technology comes in. It delivers highly-selective, robust and powerful ion separation, adding analytical performance to your existing technology.

Discover the Benefits of SelexION® DMS for Your Workflow Challenges

1. Lipidomics: Do you find unambiguous identification and quantitation of lipid molecular species in total lipid extracts difficult due to overlapping isobaric and isomeric species? SelexION technology can resolve multiple lipid classes from complex lipid matrices prior to MS analysis to enable more confident identification of lipid species and more accurate quantitation by MS/MS.

2. Peptide and Protein Quantitation: Do your peptides and proteins suffer from interferences, poor fragmentation, and lack of quality unique peptides compared to background? SelexION technology can be used to help remove sample interferences and separate isobaric peptide species, resulting in more sensitive and selective detection and quantitation of large molecule targets.

3. Small Molecule Bioanalysis and Metabolism: Are you struggling to achieve accurate and robust quantitation of small molecule therapeutics and metabolites, often complicated by matrix interferences, high baseline signal, and lack of isomer resolution? SelexION technology enables robust and reproducible bioanalytical methods, without running complex HPLC conditions or sample preparation.
