Research output: Chapter in Book/Report/Conference proceedingConference contribution


In this study, optical counter response to monodisperse fractions of ambient Los Angeles aerosols was determined. The monodisperse atmospheric aerosols were obtained using a differential mobility analyzer to select particles of a uniform geometric diameter. Instrument responses to the atmospheric aerosols were compared to responses for polystyrene latex and oleic acid particles for five sizes between 0.3 and 0.8 μm diameter. The ambient aerosol measurements were repeated during a two week period in July 1987 at Claremont, CA. The measurements were done with a Particle Measurement Systems (PMS, Boulder, CO) LAS-X optical counter of the type used for ambient aerosols size distribution determinations during the Southern California Air Quality Study (SCAQS).
