Enthalpy uses small-scale environmental chambers and EPA air testing methods to develop emissions profiles for facilities that would otherwise need to build total enclosures or use emissions factors. Our lab-scale data have been accepted by regulatory agencies in lieu of field testing.
Enthalpy's test chambers permit precise duplication of production conditions and use purified supplied air or gas mixtures with carefully chosen interior surfaces to demonstrate non-detect background levels. Emissions are reported as mass pollutant per mass of raw material and as concentrations over time.
Numerous analytical techniques are available, with FTIR spectroscopy often proving most versatile for documenting emission trends of multiple compounds. Materials emission test plans can be configured to ASTM Small-Chamber Standard D5116-06 and relevant EPA air methods.
