  • High-flow dual-channel differential mobility analyzer
    Patent number: 8919183
    Abstract: A new instrument for electrical-mobility based size segregation of particles at high resolution is described. The instrument called the high-flow dual-channel differential mobility analyzer (HD-DMA) comprises of five flows: a polydisperse aerosol flow, a clean sheath flow, two monodisperse sample flows and a residual excess flow. High resolution measurements are possible because of the large sheath flowrates that are permissible in this instrument.
