Ultimate Guide to EPA Method 202: Dry Impinger Method & CPM Analysis
Master EPA Method 202 for measuring Condensable Particulate Matter (CPM) emissions from stationary sources! In this detailed technical overview, we break down the entire methodology, sampling train configuration, and laboratory analysis procedures for EPA Method 202. Often run in tandem with filterable PM methods like Method 5 or Method 201A, Method 202 is crucial for assessing total PM2.5 compliance. What you will learn in this video: ✅ The definition of Condensable Particulate Matter (CPM) and its role in primary PM2.5 emissions. ✅ Why the EPA shifted from the old 1991 wet impinger setup to the current dry impinger method to minimize sulfate artifacts. ✅ Step-by-step breakdown of the Method 202 sampling train (condenser, water dropout impinger, and CPM backup filter). ✅ Post-test procedures: The mandatory 1-hour nitrogen (N2) purge to eliminate dissolved SO2. ✅ Laboratory sample recovery using water and hexane, followed by gravimetric analysis for organic and inorganic fractions.
