Abstract
Particle detection systems configured to identify a particle in a bulk sample volume are less efficient than those configured to measure a single particle. A particle detection system according to an inventive embodiment can identify a particle in a fluid stream. The detection system may employ one or more heating stations. Each heating station may be set to a distinct temperature. The heating stations may include a light source and a light detector, such that once a particle traverses a beam provided by the light source, the light detector may measure resultant optical scattering. Based on the optical scattering with respect to temperature or temperature variation, an identification of the single particle may be obtained, thereby eliminating measurement inaccuracies associated with bulk sample volumes. The particle detection system may detect organic particles among inorganic particles in various fluid flow environments, such as for safety or quality purposes.
