Introduction to EPA Method 5: Isokinetic Sampling Tutorial

 In this video, we break down EPA Method 5, the gold standard regulatory protocol used to determine particulate matter (PM) emissions from stationary sources. If you are preparing for your QSTI exams or working in environmental compliance, understanding the mechanics of isokinetic sampling is absolutely critical.

🔍 What We Cover in This Video:

• What is EPA Method 5 and why is it used for particulate matter?

• The principles of Isokinetic Sampling (and why matching stack gas velocity matters).

• Step-by-step breakdown of the Method 5 particulate sampling train (heated probe, filter assembly, and impinger ice bath).

• Sample recovery procedures (acetone rinses and filter handling).

• Key calculations for determining total PM concentration and ensuring isokinetic variance ($I$) stays within the mandatory $90\% - 110\%$ range.

Whether you are a stack tester, environmental engineer, or plant compliance manager, this overview will simplify the complex world of isokinetic testing.
