Web29 nov. 2024 · Over the last ten years, the coupling of ion mobility spectrometry (IMS) with MS has kept gaining momentum. In fact, IMS is sensitive to the gasphase conformations of molecules and thus, to (stereo)isomerisms. In that context, this PhD work explores the potential of high-resolution IMS approaches for structural glycosciences. WebIon mobility spectrometry (IMS) coupled with mass spectrometry (MS) is a powerful separation technique based on both their mass-to-charge ratio and the 3D structure of a protein, allowing the investigation of molecular structures in complex samples.
