Viable Non Viable Particle Counters to Fully Meet Regulatory Requirements

Monitoring viable nonviable particle counts in a cleanroom is critical to meet regulatory requirements. A facility monitoring system effectively collects, manages and reports on data from both particle counters and microbial monitors.

Total particle contamination is a mixture of nonviable and viable particles. Historically, nonviable particles are monitored continuously while viable particles have been monitored on a less frequent basis. In modern aseptic manufacturing, both types should be monitored continuously to obtain an accurate indication of the cleanroom’s condition.

An ideal monitoring program provides the sampling data required and ensures data integrity through the use of an automated system to track any changes. The system used to track and record data must meet the requirements of 21 CFR Part 11 and should be incorporated into an automated Environmental Monitoring System.
