“…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).…”
