Title: Revisions to Method 320 Measurement of Vapor Phase Organic and Inorganic Emissions by Extractive Fourier Transform Infrared (FTIR) Spectroscopy
Abstract: This proposed action would update Method 320. This method describes sampling and analytical procedures for extractive emission measurements using Fourier transform infrared (FTIR) spectroscopy in specific field measurement applications and validation tests. The EPA is proposing revisions to streamline the length and language; quality assurance/quality control procedures would be revised to reflect changes in instrumentation and sampling equipment since the original version of this method; and data processing and analysis sections would be updated to reflect evolving software and testing approaches.
