Carbon Analysis of Atmospheric Aerosols Using Grale and Reflectance Analysis
Techniques for total and elemental carbon analysis of atmospheric aerosols are described. Total carbon is determined using the gamma ray analysis of light elements (GRALE) technique which employs the in-beam measurement of γ rays emitted during the inelastic scattering of protons. Elemental carbon is determined by light reflectance. Extensive calibrations of both methods have been carried out. The use of the methods with teflon as well as glass and quartz filters is described.
