P‐97: Separation of Isomeric OLED Materials Using Ion Mobility‐Mass Spectrometry (IM‐MS)

SID Symposium Digest of Technical Papers, 2021
The separation of the structural isomers of OLED materials was carried out by using high performance liquid chromatography‐mass spectrometry (HPLC‐MS) and ion mobility‐mass spectrometry (IM‐MS). Almost all isomeric OLED materials were separated by using HPLC, however, some isomers were not distinguished with each other.

Improved analysis of derivatized steroid hormone isomers using ion mobility-mass spectrometry (IM-MS)

Analytical and Bioanalytical Chemistry, 2023
Over the last decade, applications of ion mobility-mass spectrometry (IM-MS) have exploded due primarily to the widespread commercialization of robust instrumentation from several vendors. Unfortunately, the modest resolving power of many of these platforms (~40-60) has precluded routine separation of constitutional and stereochemical isomers.

Characterization of lipid carbon–carbon double-bond isomerism via ion mobility-mass spectrometry (IMS-MS) combined with cuprous ion-induced fragmentation

International Journal of Mass Spectrometry, 2022
Characterization of phospholipid isomers is challenging due to their identical masses and similarities in structures. Here, we report that copper (I) ion complexed with phospholipids can be used to characterize both carbon-carbon double-bond (C=C bond) positional and geometric isomers. We investigate the distinct fragmentation patterns induced by the π-
