This document introduces particle counters and large particles. It addresses the question, "Are there no large particles in clean rooms?" as well as issues such as "Is it just that they are not being measured?" and includes references on gravitational settling, the particle size of contaminants that should be managed (e.g., thin films, laminating, painting processes), among others.

The "AQM Series" utilizes a high-concentration light scattering particle sensor to simultaneously measure and display/output particle count, PM equivalent values, TVOC, CO2, temperature, humidity, and atmospheric pressure. Leveraging its concentration response characteristic of 70,800,000 particles/CF, it expands air quality measurement into areas such as clean rooms, indoor environments, atmospheric environments, work environments, and exposure monitoring. The PM display is calculated from the particle size and number concentration of individual particles, allowing not only for the understanding of mass below the set particle size but also for outputting particle size distribution and short-term fluctuations (in 1-second intervals). 【Lineup】The model types have been integrated and changed.

The Particle Plus large particle-compatible particle counter detects particles ranging from 0.5 µm to over 30.0 µm. The particle counter measures airborne particles "easily," "in real-time," "by anyone," and "on-site." However, only particles with small diameters can be considered airborne, as they are affected by Brownian motion from air molecules and experience air resistance, allowing them to remain suspended for long periods. In contrast, larger particles do not continue to float and settle (fall) quickly, and they have a low occurrence frequency that does not align with the particle size distribution pattern of atmospheric dust. It is understandable that there are concerns about the phenomenon of contamination by large particles in clean rooms, as well as the issue of having small particles being acceptable while large particles are not. For a particle counter, particles that are difficult to suspend and those that fall outside the premise of isokinetic sampling are very challenging to measure. As particles increase in size, the factors contributing to gravitational settling significantly increase compared to suspension. The particle counter cannot draw in falling particles by bending their trajectory. Opening the sampling inlet and waiting for falling particles to enter is purely a matter of chance. It is essential to measure this accurately. We are always available to assist, not just for demonstrations of the measuring instrument.
