EPA Method 3 Overview | Gas Analysis & Dry Molecular Weight

 In this video, we provide a comprehensive overview of EPA Method 3, the standard protocol used to determine the dry molecular weight of stack gas emissions. Whether you are an environmental consultant, stack tester, or CEMs operator, understanding this method is crucial for accurate emissions reporting and compliance.

🔍 What We Cover in This Video:

• What is EPA Method 3 and why is it used?

• The principles of gas analysis for $O_2$, $CO_2$, and $N_2$.

• Equipment used (Orsat analyzers, Fyrite, and instrumental methods).

• How to calculate dry molecular weight ($M_d$) from gas percentages.

• Common pitfalls and quality assurance (QA/QC) tips for field testing.

EPA Method 3 is foundational for correcting pollutant concentrations to standard conditions and calculating stack gas velocity. Wrap your head around the math and procedures easily with this quick tutorial!
