ISO/TR 14644-21: Airborne Particle Sampling Techniques

This class will review the content of the newest guidance from ISO. It will look at the differences between classification and monitoring and where the two overlap, especially in light of the revisions to EU GMP Annex 1. Sampling errors are reviewed, including isoaxial and isokinetic and tubing losses in sample tubing. The proper installation of sample tubing with respect to length, bends, and connectors/valves are outlined in the session and the documents decision tree, along with several examples are given, for both advantages and disadvantages of the installation.

Understanding Particle Loss in Transport Tubing

This class will look at the mechanics of sampling errors, isokinetic and isoaxial samples, the particle loss in sample tubing as a function of variable factors, including tubing length, tubing diameter, bend radii, and connectors such as fittings and valves. A practical demonstration of performing particle loss in transport tubing will be performed [class size permitting – otherwise a review of data will be done], a review of site specific data from field examples of installed systems and what to do with the particle count data once the losses are known.
