Integrating High-Resolution Cyclic Ion Mobility Separations with Tandem Mass Spectrometry and Collision Cross Section Measurements for Human Milk Oligosaccharide Sequencing Human milk oligosaccharides (HMOs) are a biologically important class of carbohydrates responsible for promoting the healthy development of infants. However, to better understand their specific biolog...

Congrats to Dr. Habibi! Our 2nd PhD from our group!

Lastly, in the SI, we show an example of velocity relaxation where an ion mobility separation can become m/z dependent rather than mobility dependent. Fun project!

n this work, we developed reduced mass-only ion mobility separations to enable us to quantify the mass distribution component in our isotopic shifts. We also saw an ~7 Da inverse shift, where the heavier isotopologue arrived before the lighter one.

Developing Reduced Mass-Only Ion Mobility Separations to Unravel Mass Distribution-Based Isotopic Shifts Recent advancements in high-resolution ion mobility separations have enabled separations of isotopologues and isotopomers, broadly termed as isotopic shifts, based on changes in their mass distributio...
