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.
Acceptable Particle Losses in Transport Tubing
…any loss can be deemed to be unacceptable. However, let us look at the uncertainties, the acceptable errors for particle counting…
Choose the Best Methods of Particle Transport
Let’s take a look at how we can mitigate the physical forces that act on particles to ensure reliable, consistent data.
Forces and Particles
How a particle travels along tubing between a sample inlet and the particle counter is made messy by a host of physical forces. It’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?
Define Alert and Action Limits with the Latest Guidance
The transition to a continuous monitoring system now continuously demonstrates adherence to control parameters (which you use to define alert and action levels), and only instances…
Catching Up with GMP Requirements
…current good manufacturing practices (GMPs) and how they can be applied to a continuous monitoring system installed within a facility. Quality and Production teams can then establish new monitoring understandings and harmonize with standards.
How Particle Counters Work: The Technology
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.
