EPA Method 320 Instrumentation Guide

EPA Method 320 is an essential analytical technique for monitoring gaseous pollutants using Fourier Transform Infrared (FT-IR) Spectroscopy. This method allows for real-time, non-destructive analysis of various airborne contaminants, including hazardous air pollutants (HAPs) from industrial emissions. By leveraging high-resolution infrared spectroscopy, this method provides precise identification and quantification of gases across different matrices. Environmental compliance with EPA standards requires laboratories to adopt advanced FT-IR spectrometers capable of ultra-sensitive detection, minimal spectral interference, and robust software integration for regulatory reporting.

To achieve accurate gas-phase analysis, laboratories must invest in FT-IR systems with stable optical components, rapid data acquisition, and superior spectral resolution. These instruments must be capable of detecting multiple pollutants simultaneously while ensuring high reliability and repeatability. The ability to measure complex gas mixtures in real-world conditions is a critical factor in instrument selection. Below, we highlight high-performance FT-IR spectrometers suitable for EPA Method 320 applications. These instruments ensure accurate, reproducible results for emissions monitoring, environmental compliance, and industrial process control.
