Roehl, R., W. McClenny, AND R. Palmer. PHOTOACOUSTIC DETERMINATION OF OPTICAL PROPERTIES OF AEROSOL PARTICLES COLLECTED ON FILTERS: DEVELOPMENT OF A METHOD TAKING INTO ACCOUNT SUBSTRATE REFLECTIVITY. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/J-81/450 (NTIS PB83191171), 1982.

Description:

The absorptivity and imaginary index of refraction for carbon and methylene blue particles were inferred from the photoacoustic spectra of samples collected on Teflon filter substrates. Three models of varying complexity were developed to describe the photoacoustic signal as a function of filter loading and sample absorptivity.
