Our previous blogs on this topic discussed monitoring for certification and qualification. Today we address ongoing monitoring.

Our previous blog discussed monitoring for certification. Today we address monitoring for qualification. Learn more about the difference by downloading our paper Choosing the Most Suitable Particle Sample Point Locations in the Cleanroom.

Following the last blog which discussed three categories of monitoring requirements, we move onto monitoring specifically for certification.

As environmental system designers, we are often asked where to place sample points for particle monitoring, whether it be performed in a pharmaceutical cleanroom or clean device (RABS, isolator, etc.).

The previous post of the Troubleshooting for Liquid Particle Counting series was about the effects of background scatter on particle count data. This segment defines an OPC’s upper concentration limit, its role in coincidence loss, and concludes this blog series.

In the previous post of the Troubleshooting for Liquid Particle Counting series, the importance of having a constant set flow rate was demonstrated. This segment concerns the effects of background scatter.

In the previous post of the Troubleshooting for Liquid Particle Counting series, the importance of normal particle size distribution was discussed. This segment concerns the effects of flow rate deviations.

In the previous post of the Troubleshooting for Liquid Particle Counting series, specifications that provide operators quality data control were outlined. This segment concerns the importance of normal particle size distributions and the effects of flow rate deviations.

Operators can take several easy steps to ensure that quality data is collected from an optical particle counter (OPC). In this blog series, common misunderstandings and performance issues about OPCs are discussed to help the operator reach proper conclusions when questions arise about the validity of the data.
