US EPA Method 10B: Carbon Monoxide Emissions by GC/FID 

Master US EPA Method 10B for Carbon Monoxide (CO) emissions testing! This step-by-step guide covers the Method 10A sampling train setup, Tedlar bag collection, alkaline permanganate scrubbing, and GC/FID analysis with methane reduction catalyst checks for compliance and QSTI prep.

Learn the comprehensive field and laboratory workflow for US EPA Method 10B (Determination of Carbon Monoxide Emissions from Stationary Sources). While standard Method 10 relies on continuous NDIR instrumental analyzers, Method 10B utilizes an integrated gas sampling approach particularly crucial at petroleum refineries and specialized source locations. In this video, we break down how an integrated sample is extracted, passed through an alkaline permanganate conditioning system to strip out interferences like sulfur oxides and moisture, collected in a Tedlar bag, and analyzed via Gas Chromatography (GC) paired with Flame Ionization Detection (FID) after catalytic reduction to methane (CH4). Key Equipment & Chemistry Covered: • 0.25M KMnO4 / 1.5M NaOH Alkaline Permanganate Solution • Tedlar or Equivalent Integrated Gas Sampling Bags • Reduction Catalyst (Converting CO to CH4) • Flame Ionization Detector (FID) If you find these deep-dive technical overviews helpful for your field performance testing, plant compliance audits, or QSTI certifications, make sure to hit the Subscribe button!
