Fourier Transform Infrared (FTIR) Reference Spectra

The Clean Air Act Amendments (CAAA) was published in November 1990. Title III of the Clean Air Act includes a list of 189 hazardous air pollutants (HAPS) for which test methods must be established. An extractive stack sampling method, using FTIR, has been developed for measuring HAPS. As one of the initial tasks in the project development, reference spectra were developed for as many of the HAPS as possible. Attached is a table which contains the quantitative reference spectral library as of June 1993 The table includes several columns of information for each file. The pathlength is the pathlength of the sample cell used to record that particular spectrum. The TEMP column is the temperature at which the compound was measured. Spectra were recorded for each compound at for at lease two different concentrations when possible. Duplicate spectra were recorded for every concentration for quality assurance purposes. The ASC column is the accepted standard concentration which was assigned by the chemical standard. The ASC values should be used for data analysis. Duplicate samples were obtained for each concentration. These spectra were developed following the Protocol for Extractive FTIR for Analysis of Gas Emissions . Refer to the FTIR TECHNOLOGY DEVELOPMENT Report for additional information regarding the these spectra.
