Web22 mei 2024 · Hence, a mobility band-pass filter was formed by setting different electric fields in the two channels, which enables high-resolution mobility selection of analyte ions. A resolution of ca. 180 was achieved for singly charged small organic molecules, and a resolution of up to ca. 370 was achieved for multiply charged +15 myoglobin. 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.
