Using LEDs and photodiodes, the invention relies on measuring the pattern of light scattering at only a few wavelengths, but at numerous scattering angles. This enables the inference of the aerosol’s optical properties and droplet distribution, from scattering measurements.
The other systems identified during the market research does not have the capability to measure aerodynamic diameter as well as scattering to measure aerosol particles using both light scattering intensity and aerodynamic measurements that mission demands.TSI Incorporated, is currently the original equipment manufacturer (OEM) of APS Model 3321.

The aerosol light scattering measurements currently made in the NOAA Federated Aerosol Network are overwhelmingly made with one of these two instruments. Our own laboratory studies, as well as those of international workshops, have shown that the measurements produced by these two instruments are quite comparable (see, for example, Müller et al., Atmos. Meas.
Chamber exhaust is freely vented inside the ventilated enclosure.The system should be designed with a Blaustein Atomizing Modules (BLAM) nebulizer for generating aerosols from liquid solutions or suspensions.The system should include a light scattering aerosol concentration monitor, an impactor, and a gravimetric sampler, which can provide the necessary measurements to characterize the exposure to test article aerosols in use.The system also needs
