Ion Mobility Spectrometry and Tandem Mass Spectrometry Analysis of Estradiol Glucuronide Isomers

Corrole isomers: intrinsic gas-phase shapes via traveling wave ion mobility mass spectrometry and dissociation chemistries via tandem mass spectrometry.

Corrole and four of its isomers with subtle structural changes promoted by exchange of nitrogen and carbon atoms in the corrole ring have been studied by traveling wave ion mobility mass spectrometry and collision induced dissociation experiments. Significant differences in shapes and charge distributions for their protonated molecules were found to lead to contrasting gas phase mobilities, mos...

Ion Mobility Mass Spectrometry

for more complex analysers for automated sample processing and plant control. The separation time will continue to decrease; in the past there has been limited interest in fast separations but this could change as automated sample processing is developed. Increasing use of coupled techniques such as GC-GC, liquid chromatography-GC, and supercritical Suid chromatography-GC for the separation of ...

Ion Mobility-Mass Spectrometry

Selected Tandem Mass Spectrometry Ion

1 Selected tandem mass spectrometry (MS/MS) ion monitoring (SMIM) is the most 2 suitable scanning mode to detect known peptides in complex samples when an ion-trap 3 mass spectrometer is the instrument used for the analysis. In this mode, the MS detector 4 is programmed to perform continuous MS/MS scans on one or more selected 5 precursors, either during a selected time interval, or along the w...
