“…The vacuum target chamber and X-ray detection system used here are displayed schematically in Figure 3. These have been described in detail earlier (9,17), and current discussion will be kept to a minimum. The proton beam incident on the specimen is defined by three graphite collimators designed to minimize scattering.…”

Development of trace element analysis by charged-particle induced X-ray fluorescence spectrometry is reviewed, with emphasis on specimen preparation and calibration. A case is presented for the use of wet-digested specimens together with internal standards. Data on ionization cross-sections, fluorescence yields, and detector efficiencies, quantities necessary for measurements relative to internal standards, are reviewed. Experiments are described which test specimen sampling procedures, target integrity, consistency among different standards, and the accuracy and reproducibility of analytical results. Analyses of wines, biomedical specimens, and NBS orchard leaves are described. For fluids, detection limits are 0.01 to 0.1 ppm while, for wetdigested tissues, the limits relative to the original material are 0.1 to 1 ppm.The use of charged-particle beams from accelerators as a means of excitation in energy-dispersive X-ray fluorescence spectrometric analysis has received considerable attention in the past four years. Widespread interest in this

“…With "good" carbon foils, the characteristic X-ray background from trace metal impurities can be very low. This can be quantified by comparing spectra presented by Herman et al (9) from a blank foil and one with a drop of lake water evaporated on it. The foil contributed about 5 of the observed 170 ppb of Fe and 3 of the observed 32 ppb of Zn.…”

Concentrations of thirteen elements in rainwater from the Pittsburgh, Pa., area were analysed by Charged Particle Induced X-ray Emission (PIXE). They were compared to rainwater in a rural area and air particulates in Pittsburgh. Local and non-local contributions are discussed. Washout ratios were calculated and found t o be larger for smaller size particles, contrary to general belief. This work demonstrates the convenience of using PIXE.
