Comparison of Two Photoelectric Devices for Determining Sizes and Concentrations of Aerosol Particles,
Abstract
Device one collects light scattered by particles at right angles to direction of their illumination; device two collects light scattered by particles in direction near that of particle illumination. After oil droplet calibration of both devices, it was found that in the r > 0.6 micrometer region of drop radii, amplitudes of outgoing impulses from both devices are proportional to squares of sizes of particles. In the range from 20 to 0.6 micrometer the signal-to-noise ratio is 14 times greater in device two than device one.
