A syringe sampler represents the simplest delivery system for precisely delivering a sample to the particle counter. The precise motion of the syringe pump produces a steady flow of fluid that is free of pulsations…
ISO 21501-4 Calibration Overview
The introduction of ISO 21501-4, in 2007, requires the adoption of Pulse Height Analysis (PHA) particle sizing technology and particle standard spheres with international traceability and uncertainty equal to or less than ± 2.5%. The standard defines two main goals: improve the instrument-to-instrument data correlation and improve the particle count accuracy.
Should Anaerobic Cultures Be Part of GPT?
Anaerobic environmental monitoring is not a routine process, but is occasionally performed to detect potential anaerobic microbial contaminants, particularly those related to contamination by personnel.
Cleanroom Action and Alert limits
You’re going to have a high stream of data if you want a fast response to contamination events. Decide how long you want your samples to run to determine how fast. One minute samples are an immediate indicator that aren’t completely overwhelming…
Best Particle Counter for Sampling 5.0 μm Particles
As the aerosol particle counting experts, Particle Measuring Systems recommends against the use of 0.1 CFM particle counters to sample and monitor 5.0 μm particles. Instead, use a 1.0 CFM flowrate model like the Lasair® III particle counter to provide an adequate sample for the detection of 5.0 μm particles.
VHP Resistance and IsoAir® Pro Series Particle Counters
Vaporized Hydrogen Peroxide is a strong oxidizing agent and has been proven as a sterilizing agent in enclosed filling isolators for many years. As the increase of applications using isolators increases, so does the need for robust sensors capable of withstanding these environments. IsoAir® Pro Remote Particle Sensors contain an internal flow path that is designed to be resistant to the harmful effects of VHP.
Considerations and Steps for Building a Contamination Control Strategy – Series Part 4 of 4
Conventional approaches to contamination control are changing. They are being driven by the need to anticipate contamination events, rather than simply react to them, and new regulations are supporting this shift in thinking. Defining a Contamination Control Strategy (CCS) is unique for each process and requires an intimate understanding of both the process and how to implement an effective strategy. This blog series goes into depth on both topics.

Airborne Molecular Contamination (AMC) Control in Precision Optical Lens Manufacturing
Real-time AMC monitoring in the optical component and sub-system manufacturing facility becomes a leading indicator of effective quality and reliability of the component and sub-system.
Lithography Defects Caused by AMC (Airborne Molecular Contamination) in the Functional Area
There is a need for more control of deleterious environmental contamination, including better detection and real-time response to undesired AMC concentration levels, the most prevalent of which are the amines class of AMCs.
