EPA Reference Spectra Interferograms

Listed below are the interferograms from which the EPA Reference Absorbance Spectra were created. Single beam spectra can be created from these interferograms by using the FTPROC program avalible on this site. The Background Interferograms are those interferograms recorded while the absorption cell was evacuated. The Data Interferograms are those interferograms recorded with the analyte present in the absorption cell. The CTS Interferograms are those associated with the recording of the absorption of the Calibration Transfer Standard gas. For more information on the recording of the interferograms please see the report FTIR TECHNOLOGY DEVELOPMENT. The file naming convention used on the interferograms is the same used on the EPA Refernce Absorbance Spectra.
