Ion Mobility Spectrometry : Optimization of Parameters in Collision Cross Sections and Trace Detection of Explosives
… in CCS. The accurate calculation of the collision cross section for multiple molecules is a long-time interested topic in the research for substances detection in micro scale. No reliable analytical approach to calculate the collision cross section has been established to date. Different …

Consistent treatment of transport properties of weakly-ionized gas mixtures in DSMC
… of mass, momentum and energy during binary collision processes between the simulated particles. The details of the collision processes, and therefore, the transport properties are dictated by the collision cross-section models employed in DSMC. In the DSMC method, phenomenological models are …

Utility of Ion Mobility – Mass Spectrometry in Peptidoglycan Structural Determination
… Potential isomers, modifications, and cross-linking patterns within whole cell digests lead to complex samples that typically require manual analysis. The introduction of a method for streamlining the identification of peptidoglycan components (muropeptides) is needed to develop a …

Ion Mobility and Gas-Phase Covalent Labeling Study of the Structure and Reactivity of Gaseous Ubiquitin Ions Electrosprayed from Aqueous and Denaturing Solutions
… with selective covalent structural probes. Collision cross-section (CCS) distributions were measured prior to ion/ion reactions to ensure the ubiquitin ions were not unfolded when they were introduced to the gas phase. Ubiquitin ions were electrosprayed from aqueous and methanolic solutions …

SOLVATION OF ORGANIC CATIONS IN THE GAS PHASE AND WITHIN MOLECULAR CLUSTERS
… by comparing the experimentally measured collision cross section values with those predicted from DFT computations.

Development of Ion Mobility Mass Spectrometry Instrumentation to Investigate the Gas-Phase Structures of Protein and Protein Complex Ions
… technique that separate ions based on their collision cross section (a description of ion shape) and mass-to-charge ratio. Electrospray ionization of samples from buffered solutions at biologically relevant pH generates “native-like” protein ions, which retain noncovalent interactions and …
