PLAIR publishes in the PDA Journal of Pharmaceutical Science and Technology

We are thrilled to announce the publication of our peer-reviewed data examining the impact of sampling flow rates for total particle counting in Grade A aseptic environments.

This is a major milestone for the pharmaceutical manufacturing industry.

Biofluorescent particle counters that deliberately avoid using a concentrator (virtual impactor) to prevent missing contamination due to its associated losses can now also be used as total particle counters.

Our latest study provides scientific substantiation for this: under homogeneous, unidirectional airflow conditions (Grade A and comparable B environments), a lower sampling flow rate, such as 2.83 L/min, delivers total particle monitoring performance comparable to 28.3 L/min, a rate codified in the latest Annex 1 independently of recent advances in direct sampling technology.

These findings support the adoption of BFPC technology to enable safer, more efficient, and simultaneous monitoring of viable and total particles in critical Grade A zones, fully aligning with Annex 1's objective of improved patient safety.
