Identifying Fenton-Reacted Trimethoprim Transformation Products Using Differential Mobility Spectrometry
Psutka, Jarrod; Dion-Fortier, Annick; Dieckmann, Thorsten; Campbell, J. Larry; Segura, Pedro; Hopkins, W. Scott (ACS Publications, 2018-04-17)A transformation product of trimethoprim, a contaminant of emerging concern in the environment, is generated using an electro-assisted Fenton reaction and analyzed using differential mobility spectrometry (DMS) in combination ... -
A parallelized molecular collision cross section package with optimized accuracy and efficiency
Ieritano, Christian; Crouse, Jeff; Campbell, J. Larry; Hopkins, W. Scott (Royal Society of Chemistry, 2019)Ion mobility-based separation prior to mass spectrometry has become an invaluable tool in the structural elucidation of gas-phase ions and in the characterization of complex mixtures. Application of ion mobility to structural ... -
Unravelling the factors that drive separation in differential mobility spectrometry: A case study of regioisomeric phosphatidylcholine adducts
Ieritano, Christian; Campbell, J. Larry; Hopkins, W. Scott (Elsevier, 2019-10)Differential mobility spectrometry (DMS) has shown promise as an analytical tool in the field of lipidomics. However, the underlying mechanism that drives DMS-based lipid separations is still somewhat unclear. Here, we ... -
Using differential mobility spectrometry to measure ion solvation: An examination of the roles of solvents and ionic structures in separating quinoline-based drugs
Liu, Chang; Le Blanc, J. C. Yves; Shields, Jefry; Janiszewski, John S.; Ieritano, Christian; Ye, Gene F.; Hawes, Gillian F.; Hopkins, W. Scott; Campbell, J. Larry (Royal Society of Chemistry, 2015)Understanding the mechanisms and energetics of ion solvation is critical in many scientific areas. Here, we present a methodlogy for studying ion solvation using differential mobility spectrometry (DMS) coupled to mass ...
