40th Aerosol Society Conference 2025 (Himeji - August 27 to 29) Update

パーティクルプラス
This is the material used at the luncheon meeting of the Japanese Aerosol Society (JAAST) held at the Himeji Chamber of Commerce from August 27 to 29 (although it was not displayed on the screen due to system issues). While light scattering particle counters have aspects that are not well-suited for aerosol measurement, they have become essential in the field of contamination control, where in-situ capability, compact size, and ease of use are required. However, they are primarily used in clean rooms, and measuring larger particles in a wider range of environments was previously considered unconventional. We have been using particle plus fine particle counters that can handle high particle concentrations and larger particles in various harsh environments, accumulating various insights. This is a simplified document summarizing some of those insights.
