Single-particle optical sensing (SPOS) was originally developed for the field of particulate contamination analysis. Particles in a liquid suspension flow through a small "photozone", a narrow, ...

Some professionals working with particle counters believe it to be necessary to divide the particle counts of non-volumetric particle counters by the counting efficiency (CE) at the lower limit when ...

This is especially relevant given the recent revision to EU Annex 1 – Manufacture of Sterile Medicinal Products (2022). The Technical Report (TR) outlines how particle counters are used to monitor and ...

The latest instruments could be provided by a new vendor or the existing manufacturer. It is common for new models to be sourced due to product obsolescence or enhanced specifications, even when the ...

Particle counting systems help monitor airborne contamination and support quality assurance in critical production environments.
