EPA Method 17 Overview | In-Stack Particulate Matter (PM) Determination

A comprehensive overview of USA EPA Method 17, the standard reference method for determining particulate matter (PM) emissions from stationary sources using an in-stack filtration assembly. Unlike EPA Method 5, which uses a heated probe and an out-of-stack filter, Method 17 samples particulate matter isokinetically by placing the filter holder directly inside the stack or duct. This video breaks down the core principles, equipment requirements, operational constraints, and exact procedures for successful source evaluation. 📌 What You'll Learn: • The core principles of EPA Method 17 and in-stack sampling • Method 17 vs. Method 5: Key differences, advantages, and temperature limits • Equipment configuration (thimbles, glass fiber filters, and condenser systems) • Step-by-step isokinetic sampling procedures and leak-checking • Gravimetric analysis and final PM concentration calculations If this overview helped you understand the nuances of in-stack particulate sampling, please give the video a thumbs up, leave your field questions in the comments, and subscribe for more specialized environmental engineering and source testing guides! #EPAMethod17 #StackTesting #qstiprepacademy #ParticulateMatter #AirEmissions #EnvironmentalEngineering #Method5 #IsokineticSampling
