  2. 1. New applications and developments of field-asymmetric ion mobility spectrometry - mass spectrometry (FAIMS-MS)

    Author : Axel Mie; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; triazine; enantiomer; ion focusing; ion mobility; FAIMS; DMS; axial ion inlet;

    Abstract : Field asymmetric ion mobility spectrometry (FAIMS), also commonly termed differential mobility spectrometry (DMS), is a gas-phase ion separation technology. FAIMS exploits differences in high-electric-field to low-electric-field ion mobility ratios to discriminate between ion species. READ MORE

  5. 3. Characterizing ions in solution by NMR methods

    Author : Marianne Giesecke; István Furó; Peter Griffiths; KTH; []
    Keywords : electrophoretic NMR; diffusion NMR; NMR imaging; ion pairing; ion association; polyethylene oxide; metal-ion complex; Li ion batteries; electrolyte characterization; Kemi; Chemistry;

    Abstract : NMR experiments performed under the effect of electric fields, either continuous or pulsed, can provide quantitative parameters related to ion association and ion transport in solution.  Electrophoretic NMR (eNMR) is based on a diffusion pulse-sequence with electric fields applied in the form of pulses.

  6. 4. Protein stability and mobility in live cells : Revelation of the intracellular diffusive interaction organization mechanisms

    Author : Xin Mu; Mikael Oliveberg; Johan Elf; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusive interactions; macromolecular crowding; protein thermodynamic stability; protein mobility; in-cell NMR; Hofmeister series; Biochemistry; biokemi;

    Abstract : Biochemical processes inside living cells take place in a confined and highly crowded environment. As such, macromolecular crowding, one of the most important physicochemical properties of cytoplasm, is an essential element of cell physiology. READ MORE

  7. 5. Advances in Mass Spectrometry for the Analysis of Emerging Persistent Organic Pollutants

    Author : Lauren Gayle Mullin; Leo W. Y. Yeung; Ingrid Ericson Jogsten; Jean-François Focant; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Liquid Chromatography; Supercritical Fluid Chromatography; Ion Mobility; POPs; Electrospray Ionization;

    Abstract : Mass spectrometry (MS) is a technique widely implemented for the measurement of environmental pollutants. A critical tool for the analysis of persistent organic pollutants (POPs) over several decades, MS as coupled with liquid and gas chromatography (LC and GC) techniques enables the analysis of emerging POPs.
