Airborne Particle Sampling Techniques

Understanding ISO/TR 14644-21:2023

The Importance of Accurate Sampling Techniques

Delve into the intricacies of ISO/TR 14644-21:2023, the pivotal technical report that sets forth the standards for airborne particle sampling in cleanrooms and controlled environments. This document is the cornerstone for ensuring compliance with ISO 14644-1:2015 for cleanroom classification and ISO 14644-2:2015 for particle monitoring, providing a framework for capturing precise data to support air cleanliness verification. It’s not just about meeting regulatory requirements; it’s about embracing a methodology that safeguards the integrity of your processes and products.

Sampling Quality vs. Data Quality

Balancing Sample Integrity with Data Precision

ISO/TR 14644-21:2023 advocates for direct sampling methods as the gold standard for minimizing sample loss and contamination. This approach eliminates the need for lengthy tubing, which can compromise sample quality, especially when dealing with larger particles. Our comprehensive overview provides insights into the advantages of direct sampling and offers practical advice on implementing these techniques to capture the most representative samples from critical locations within your cleanroom.

Isokinetic Sampling

Achieving Representative Sampling in Unidirectional Airflow

Isokinetic Sampling is essential for obtaining an accurate representation of airborne particles within a cleanroom’s unidirectional airflow. This technique ensures that the sampled air velocity matches the surrounding airflow, thereby preventing particle distortion and loss. Our detailed section on Isokinetic Sampling will guide you through the process of setting up an optimal sampling environment, helping you to achieve the precision required for thorough and reliable cleanroom validation.
