The preferred compliance test for measuring formaldehyde in stack emissions is EPA Method 320. Formaldehyde-containing spike gas is introduced from a cylinder directly into the stack flue gas. This Formaldehyde calibration gas can be used to calibrate the FTIR spectroscopy used to measure the recovery of spike gas to demonstrate that the stack gas formaldehyde concentration is representative and accurate.
Airgas operates its own dedicated blending facilities as well as maintains a national network of blending technology to ensure accurate, consistent production.
