Abstract / Description of output

A cyclone impactor has been modified to include an ionizing radiation source and a SAW device in place of the usual filter. The SAW has been incorporated in an oscillator circuit and, with a chemical treatment of the collection plate, the real time response to particulate matter is demonstrated.
