Abstract
Various embodiments include methods and systems to dilute a sampled particle-laden aerosol stream in a recirculating type of aerosol diluter system. In one embodiment, a system to dilute a sampled aerosol stream includes an aerosol sample inlet. A primary diluter device includes a first inlet to receive the aerosol stream and a second inlet to receive a filtered portion of the aerosol stream and combining the filtered portion with an additional sampled aerosol stream. A flow diverter device splits at least the sampled aerosol stream into a first portion of the sampled aerosol stream and a remaining portion of the sampled aerosol stream. A filter receives the remaining portion of the sampled aerosol stream and provides a filtered aerosol stream to the second inlet of the primary diluter device. Other methods and apparatuses are disclosed.
