The present contribution focuses on measurements of soot nuclei by: a) thermophoretic sampling on fine wires followed by microscopy analysis and b) high-dilution probing followed by High-Resolution Differential Mobility Analysis (HR-DMA).
A comprehensive investigation was conducted on a sooting ethylene laminar premixed flame: the present contribution focuses on the characterization of the gas composition by gas microsampling and GC/MS analysis, and of soot properties by optical measurements; Part II presents detailed measurements of soot nucleation by thermophoretic sampling and differential mobility analysis.
Bacher, G. et al. Charge-reduced nano electrospray ionization combined with differential mobility analysis of peptides, proteins, glycoproteins, noncovalent protein complexes and viruses.
Particle dimension, crystal phase and surface morphology were characterized using differential mobility analysis, Raman spectroscopy and atomic force microscopy, respectively.
Differential mobility analysis.
The size of nanoparticles can be analyzed by various methods such as dynamic light scattering (DLS), atomic force microscopy (AFM), transmission electron microscopy (TEM), scanning electron microscopy (SEM), differential mobility analysis (DMA), and small angle X-ray scattering (SAXS) [15].
This technology, variously referred to as electrospray ionization-ion mobility spectrometry (ESI-IMS), nanoelectrospray gas-phase electrophoretic mobility molecular analysis (nES-GEMMA or GEMMA), electrospray-differential mobility analysis (ES-DMA), or macroion mobility spectrometry (macroIMS), was once available primarily to mass spectrometrists.
If mobility responses differ between health and skill groups, some of our results could potentially be driven by differential mobility rather than by differential employment responses.
Particles were classified according to their mobility diameters by a differential mobility analyzer, followed by thermophoretic sampling by scanning electron microscopy to investigate their carbon black morphologies.
Unipolar charger is a crucial component in the aerosol particle sizing system by electrical mobility analysis.
