“…Note that the ROMIAC further features the isopotential aerosol inlet and sampling outlet, which may potentially reduce the particle/ion loss due to the electrical charge-up of insulation used in typical DMAs. Similar ideas of tilting the flow direction were adopted by several other designs, such as the nanoparticle crossflow DMA (NCDMA) in a cylindrical configuration [62], and the crossflow ion analyzer [63]. No experimental data were published.…”

Differential mobility particle sizers (DMPSs) are instruments for online sizing gas-borne particles in submicrometer and nanometer diameter ranges. The aerosol charger, the differential mobility analyzer (DMA), and the particle concentration detector are three essential components in DMPSs. In the past four decades, the design of DMAs has evolved into a variety of modern versions to extend their sizing limits, especially in lower detectable size limits. The DMAs are now capable of classifying or sizing particles in the diameters down to 1.0 nm. This article gives a brief overview of state-of-the-art DMAs particularly designed for classifying particles with sizes down to sub-10 nm.

“…The differential mobility analyzer (DMA) has become a key instrument for these purposes. Since the pioneering studies of Hewitt (1957) and Knutson and Whitby (1975) for submicron aerosols, different DMA configurations and strategies have been proposed to tackle the study of highly diffusive nanoparticles and ions, among others Kousaka, Okuyama, and Mimura (1986), Rosell-Llompart, Loscertales, Bingham, and Fernández de la Mora (1996), Chen et al (1998), Loscertales (1998), de Juan and Fernández de la Mora (1998), Alonso (2002), Martínez-Lozano and Fernández de la , Song and Dhaniyala (2007).…”
