Abstract

Response calculations for five commercial light-scattering aerosol particle counters have been carried out that take into account the emissive power of the light source, the spectral sensitivity of the phototube, and the specific geometrical factors for each instrument. Earlier calculations had been published for two of these instruments, but these had not considered each of these factors appropriately. The results indicate a strong dependence of response upon both the real and imaginary part of the refractive index and, for a given refractive index, a multivalued response in the submicrometer range for three of the five instruments.
