FTIR Spectroscopy for Greenhouse Gas Inventories

EPA estimates 13,000 sources are subject to the proposed Mandatory Greenhouse Gas Emission Inventory Reporting Rule. Numerous facilities will be required or elect to test for greenhouse gases (GHGs).

Enthalpy provides fast, reliable, and defensible analytical services for GHGs of regulatory interest.

Enthalpy's FTIR spectroscopy group offers real-time onsite techniques for maximum accuracy and quality assurance. We also provide cost-effective in-lab approaches when compliance level data are not required.

Example Recovery Efficiencies in Tedlar bags




Enthalpy's FTIR credentials include over four hundred field tests since 1996, unmatched equipment resources, and an FTIR program director nationally recognized for developing FTIR technology and test methods. Recent GHG inventory projects include semiconductor facilities, nitric acid plants, and municipal waste combustors.
