Effect of Precise Control of Drift Gas Composition for a U-shaped Mobility Analyzer [PDF]
Ion mobility coupling with mass spectrometer has become an important tool for analysis of complex mixtures. Generally, the type and composition of drift gas (e.g., N2, He, CO2) in an ion mobility spectrometer will impact on the separation of different ...

Plasma Metabolomic Profiling Reveals Four Possibly Disrupted Mechanisms in Systemic Sclerosis
Systemic sclerosis (SSc) is a rare systemic autoimmune disorder marked by high morbidity and increased risk of mortality. Our study aimed to analyze metabolomic profiles of plasma from SSc patients by using targeted and untargeted metabolomics approaches.

Fragmentation and Mobility Separation of Peptide and Protein Ions in a Trapped-Ion Mobility Device [PDF]
Ion mobility separations (IMS) have increasingly been coupled with mass spectrometry to increase peak capacity and deconvolute complex mass spectra in proteomics workflows. IMS separations can be integrated prior to or following the collisional activation step.

A high transmission axial ion mobility classifier for mass-mobility measurements of atmospheric ions [PDF]
Abstract. We present an electrical mobility classifier for mass-mobility measurements of atmospheric ions. Size segregation coupled with mass spectrometric detection of naturally occurring ions in the atmosphere is challenging due to the low ion concentration.
