Structure, principles, and calibration of introductory particle counters.

A particle counter that plays an active role in measuring cleanliness in clean rooms and general environments, as well as in trend monitoring! We will introduce its principles, including a comparison with photometers.

This document introduces the structure, principles, and calibration of particle counters as an introductory guide. A "particle counter for airborne particles" is a device used to measure the number of suspended particles, particle size, and particle size distribution in clean rooms, indoors, and outdoors. It quantitatively aspirates sample air, introduces it into the laser irradiation area, and detects the scattered light from each irradiated particle. From the intensity of the light scattering response, the particle size is determined, and the number of particles in the sample air per unit time and unit volume, as well as the particle size distribution, is displayed. We have included "conceptual diagrams of particle sensor structures" and "dispersal performance of particle sensors," so please take a look at them by downloading the PDF.
