The lowest detectable limits of the various elements for the external beam PIXE method were investigated. The observed sensitivity for ashed biological tissue or blood samples varies from 0.01 to 0.5 ppm for Z varying from 20 to 45 for the K-lines and similarly for Z from 50 to 90 for the L-lines. Gaseous targts are analysed by irradiation in a special cell. The sensitivities vary between 1 and 10 ppm at atmospheric pressure. Liquid samples are prepared by liquid deposition on various porous backings and the observed detectable limits are again in the sub-ppm level. Finally, sensitivities of 1–10 ppm, and selectively up to 0.1 ppm, have been obtained for thick ore samples.
