The quantitative elemental analysis of small particles can be performed in the transmission electron microscope by use of an energy dispersive X-ray detector and multichannel analyzer. As recently suggested by Cliff and Lorimer (1), Equation 1is used to determine a calibration curve of X-ray intensities relative to silicon for the accurate chemical analysis of thin particles. In this equation, I1 and I2 are the measured characteristic X-ray intensities of the two elements in question, C1 and C2 are the weight fractions and k is a proportionality constant. Absorption, atomic number and fluorescence corrections in transparent particles are assumed to be negligible at an electron accelerating voltage of 100 keV.

AbstractProton scattering quantitative elemental analysis is examined as a complement to proton induced X-ray emission analysis for air particulate samples. Both methods are absolute, non-destructive, and are suitable for use on samples up to about 1 mg/cm2 in areal density. Characteristics of the method are discussed and examples of aerosol spectra are presented.
