TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Currently there are no tools to monitor the size or concentration of nanometer to submicrometer particles aboard spacecraft cabins. Yet there are many sources aboard the spacecraft known to generate particles in this ultrafine size range. Our technology provides a means to make this measurement in a compact, low power, unit that may be made suitable for spacecraft. With a newly developed, self-sustaining water-based condensation particle technology, particles from the nanometer to micrometer size range are enlarged through water condensation and counted optically. Yet, unlike other condensation-based counters, our unit recovers all of the evaporated water within the wick itself. It needs no water reservoirs, and can be operated in any orientation. All water transport is by capillary action, and gravity is not needed. Coupled with a size selection device it can provide data on mean particle size. Measurable concentrations are from 1 to 1 million particles per cubic centimeter. We aim to adapt our existing technology to the long-term, zero-gravity, robust monitoring needed by NASA. Specific objectives are to verify a prototype self-sustaining condensation particle counting system that can be operated in any orientation; that can detect and count individual particles from 10 to 2000 nm; that contains the controls and on-board diagnostics to ensure long-term performance; and whose critical components are compatible with an ultimate package weighing less than 2 kg, and requiring less than 4 watts of power.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA will use this instrument to monitor airborne particle environmental in manned spacecraft. Such data is needed (1) to establish the levels and sources of airborne particulate to which crew are exposed, and (2) to provide a signature of background levels to enable earlier detection of smoke particles from fires.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Because it is tippable, and emits no toxic fumes, this instrument would be uniquely suitable for measuring concentrations on moving platforms, inside aircraft, on school buses, or in indoor environments such as offices and schools. It would be used for community monitoring networks, and by aerosol research laboratories as a handy, non-toxic measurement.
