NewsParticle Data Collection and Interpretation for ISO Cleanrooms

BLOG: Particle Physics and Forces in Tubing

How a particle travels along tubing between a sample inlet and the particle counter is made messy by a host of physical forces. Itā€™s so messy, validating this sample tubing can be difficult. So what are these forces, what are the losses, and what are the acceptable results? Particle Physics…

BLOG: How do Particle Counters Work?

Regardless of manufacturer, the technology behind these devices uses the principle of light scattering. In this blog, we look inside the equipment to see how particle counters work.

How Tubing Affects Particle Counts

Multiple mechanisms emerge when sample tubing of any length is placed between the sampling location and the particle counter inlet probe. By standardizing set-up variation where possible, these mechanisms are further classified into their principal loss mechanisms.

Particle Sampling with Isoaxial and Isokinetic Airflow

PMS discusses the air sampling conditions required to compare particle data. What does isoaxial and isokinetic flow mean for a cleanroom particle counter, and how does it impact the comparison of counts?
