Determination of Aerosol Particle Size Distribution using Electrical Differential Mobility Analyzer (DMA)
Introduction: Determining the size distribution of the particles for assessing their effects on human health and their control mechanisms is very effective. One of the most important equipment used in determining particle size distribution is the DMA. In this study, in addition to the design and construction of a DMA, the size distribution measurement of aerosol particles was carried out. Mate...
متن کاملDirect Study of the Particle Differential Mobility Analyzer (DMA) Systems: a review article
Background & Aim: One of the unknown equipment inside our country, especially for researchers, is the DMA system, which used to particle size distribution, especially for nanoparticles. The purpose of this paper was to review the studies carried out in this field, assessment of the evolution and importance of the application of this system and introduce the true position of this system among re...
متن کاملAccelerated high-resolution differential ion mobility separations using hydrogen.
The resolving power of differential ion mobility spectrometry (FAIMS) was dramatically increased recently by carrier gases comprising up to 75% He or various vapors, enabling many new applications. However, the need for resolution of complex mixtures is virtually open-ended and many topical analyses demand yet finer separations. Also, the resolving power gains are often at the expense of speed,...
متن کاملA study on effects of size and structure on hygroscopicity of nanoparticles using a tandem differential mobility analyzer and TEM
A. L. Miller National Institute for Occupational Safety and Health/ Spokane Research Lab, Spokane, WA 99207, USA Abstract A hygroscopicity tandem differential mobility analyzer (HTDMA) technique is used to determine size-effect of nanoparticles (NaCl, (NH4)2 SO4, KCl, NH4NO3, MgCl2, CaCl2) on their hygro scopic properties (deliquescence relative humidity (DRH) and hygroscopic growth factor (GF...
متن کاملA novel tandem differential mobility analyzer with organic vapor treatment of aerosol particles
A novel method to characterize the organic composition of aerosol particles has been developed. The method is based on organic vapor interaction with aerosol particles and it has been named an Organic Tandem Differential Mobility Analyzer (OTDMA). The OTDMA method has been tested for inorganic (sodium chloride and ammonium sulfate) and organic (citric acid and adipic acid) particles. Growth cur...
