High-resolution separation of bioisomers using ion cloud profiling

Nature Communications, 2023
Ion mobility is used in mass spectrometers for structure analysis of biomolecules. Here, the authors show that ion mobility analysis in an ion trap under ultra-high fields enables isomer separation at resolutions over 10,000, wich they demonstrate for ...
