Particle measurements in ultra-pure water (UPW) systems can take a long time to return to a stable baseline after normal operations are interrupted by an event such as maintenance shutdowns. A ...

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 ...

STEMart's Particulate Matter Testing uses two methods, the Light Obscuration Particle Count test and the Microscopic Particle Count test. The former test is adapted from the United States Pharmacopeia ...

Optical particle counters (equipment here from Pacific Scientific), now with ISO standard calibrations, determine the condition of hydraulic oils used in injection machines and ensure comparability of ...
