  • Wide range, very high resolution differential mobility analyzer (DMA)
    Patent number: 7521673
    Abstract: The resolution of a differential mobility analyzer (DMA) and the range of valid mobility values for the charged particles that it can detect are increased. The DMA makes use of a flat configuration and a purely two-dimensional operating model in which shims are used for improved adjustment and precision of the parallel faces that make up the analysis area. The analyzer uses a closed and pressurized aerodynamic tunnel to establish a cross flow with a very high Reynolds number.
