By forward alpha scattering technique (FAST) light elements, from hydrogen through fluorine, are shown to be determined nondestructively and simultaneously, though these elements cannot be measured satisfactorily by any other physical method. We have studied on the app-lication of this method to atmospheric aerosol, photochemical aerosol, etc. It was assured that the whole mole ratio of aerosol can be determined by the cooperative application of the FAST and the conventional fluorescent X ray analysis. FAST has been realized to give the water content of aerosol, although the sample should be analyzed in vacuum.
