Conventional DLS instruments use a detection angle of 90°. The concentration limit of instruments using such optics is very low, as multiple scattering effects need to be eliminated. Multiple ...

The process of sizing and counting particulates in a sample is called particle measuring and can be performed in either liquid or air. Industrial processes such as semiconductor wafer fabrication use ...

Today’s standards define airborne particle monitoring in units of particles per cubic meter (particles/m 3). These standards tend to require sampling an entire cubic meter (1 m 3) to establish an ...

The mind-bending laws of quantum mechanics say we can't observe the smallest particles without affecting them. Physicists have now caused the smallest-ever disturbance while making a quantum ...

EMS is a leader in the cleanroom industry, delivering complete cleanroom monitoring and control solutions, services to customers, and ensuring quality by design from inception to process control.

Upon completion of the evaluation, it was determined that PMS passed with zero deficiencies. “Most initial assessments are completed with an average of eight to ten deficiencies, that we passed with ...

Don Lincoln is a senior scientist at the U.S. Department of Energy's Fermilab, the country's leading particle physics research institution. He also writes about science for the public, including his ...

Aim: Sampling, sample preparation, and off-line measurement are inconvenient steps for particle size characterization, as they require trained operators, method validation and sometimes transport to ...

Particle Measuring Systems, Inc. announces the acquisition of Environmental Monitoring Services Irl. Limited and EMS Particle Solutions Ltd, and their parent company (collectively EMS); established in ...
