Characterization of airborne particulates by pyrolysis/mass spectrometry and carbon-14 analysis

Pyrolysis/mass spectrometry (Py/MS) has been used to characterize the composition of organics in an ambient air particulate sample from the eastern Utah oil shale lands. The procedure involved collection of the individual contributors, pyrolysis of these samples, and finally a least-squares fitting...

Zusammenfassung:	Pyrolysis/mass spectrometry (Py/MS) has been used to characterize the composition of organics in an ambient air particulate sample from the eastern Utah oil shale lands. The procedure involved collection of the individual contributors, pyrolysis of these samples, and finally a least-squares fitting of the individual contributor spectra to the pyrolysis mass spectrum of the ambient sample. The Py/MS results were verified by using /sup 14/C analysis.
