Abstract
Progress is described for the first year of a two year effort to fabricate a high-speed aerosol analysis system. Twelve automated dichotomous sampling stations which collect particles in the 0 to 2 and 2 to 20-micrometer diameter ranges will be built. An evaluation of a prototype virtual impactor for aerodynamically separating particles into two size ranges is given. Design improvements for minimizing losses are described. Design parameters have been determined for a high-speed energy dispersive X-ray fluorescence spectrometer capable of analysis of elements with atomic numbers above 13. A prototype beta gauge for total mass determination has been tested, and a detection limit of 10 microgram/sq cm has been measured. For the purpose of sample identification, a system is described by which the X-ray spectrometer and the beta gauge will be able to identify a digital code marked on each filter.
