Question:Ā āWhat is the need of taking a non-viable particle count after a power outage for an hour. Our Class C area is stabilizing after 30 minutes of a power cut?ā There are several reasons for deploying your Non-Viable Environmental Monitoring Program following a power outage, but primarily it is to…
Glen Slayter,Ā IntelĀ and Dan Rodier, Particle Measuring Systems (PMS) presented this paper at the 2020 Ultrapure Micro event. This Intel case study discusses the benefits and challenges of monitoring particles in ultrapure water (UPW) down to 20 nm. The presentation was theĀ recipientĀ of theĀ #UPM2020Ā best presentation award. Only Particle Measuring Systems has…
ISO 21501-4 is the recognized standard for optical particle counter calibration. In this blog, we look at the basics of the ISO 21501-4 standard for those new to particle counter calibration. Why do I need to care about ISO 21501-4? Your aerosol particle counter is going to need calibration…
How a particle travels along tubing between a sample inlet and the particle counter is made messy by a host of physical forces. Itās 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…
