FTIR Technology (From: Technology Transfer NetworkEmission Measurement Center)

The Emission Measurement Center (EMC) at EPA has been investigating the application of Fourier Transform Infrared Spectroscopy (FTIR), to emissions monitoring. The FTIR technology shows promise since it has the capability to measure more than 100 of the 189 Hazardous Air Pollutants(HAPs) listed in Title III of the Clean Air Act Amendments of 1990 (CAAA).Upon passage of the CAAA, measurement methods existed for only 40 of theHAPs. The FTIR has the capability of measuring multiple compounds simultaneously, thus providing an advantage over current measurement methods which measure only one or several HAPs; FTIR Methods can provide a distinct cost advantage since it can be used to replace several traditional methods(cost savings can vary depending on the number of compounds present).
