Abstract Differential mobility analyzer (DMA) is an essential equipment for aerosol researchers. Several different types of DMA have been developed and widely used. Generally, DMA basically consists of two concentric cylindrical columns. In this configuration a long column is needed for a large size particle generation or measurement. To overcome this problem, we developed toroidal type DMA. With this configuration and height of 8 cm and width of 14 cm, the operating range becomes similar to a standard long DMA. More detailed performance characteristics of Hy-DMA will be presented at the conference.
