Thermodynamics by the pool
Summer weather has finally reached Finland, so yesterday I decided to move the office to a near-by outdoor swimming facility. The poolside was quite a good place to think about thermodynamics, as it provides several every-day examples of some of the relevant phenomena: the water evaporating from the skin and creating cold shivers tells us about the latent heat in phase transitions. The kids ...

Best Particle Counter for Sampling 5.0 µm Particles
As the aerosol particle counting experts, Particle Measuring Systems (PMS) recommends against the use of 0.1 CFM particle counters to sample and monitor 5.0 μm particles. Instead, the best particle counter has a 1.0 CFM flowrate model such as the Lasair Pro Particle counter to provide an adequate sample for the detection of 5.0 μm particles. ...

On measurement of particle size distribution of sub 5 nm aerosol particles
Nano particles have been sized based on their electrical mobility. This is not efficient because most of the nano particles are electrically neutral. Measuring the particle size distribution typically consist of detecting size selected particles with an aerosol particle detector such as Condensation Particle Counter (CPC). This is also the working principle of Scanning Mobility Particle Sizer. ...

Selecting an Airborne Particle Counter: Types of Monitoring (Series Part 2 of 4)
Frequent or Continuous? Frequent Monitoring To demonstrate compliance to ISO, frequent monitoring requires sampling at specified time intervals not exceeding 60 minutes during operation. Manifold systems are the least expensive solution and usually installed during the cleanroom construction process. Standalone particle counters may be installed at any time. A manifold system includes either 16 ...

Manifold Particle Monitoring: Improved Accuracy
The Lasair III Aerosol Particle Counter is the latest generation of aerosol particle counter from Particle Measuring Systems. The Aerosol Manifold II is designed to work with the Lasair III counter under the control of Particle Measuring Systems facility monitoring software (Facility Net). The Lasair III particle counter uses a patented pressure measurement system to avoid the undercounting ...

The Steps of a Risk Assessment for an Aseptic Filling Line
Here, we will discuss the steps of a risk assessment for an aseptic filling line. Classification First, lock down the classification of your cleanroom. Classification: Is a method of assessing the level of cleanliness against a specification for a cleanroom or clean zone. Should be clearly differentiated from operational process monitoring. Should tell you the number and location of ...
