Concentrations of about 30 elements in 7 certified reference materials (NIES No. 1, 2, 3, 7, 8, 9, 10a, b, c) prepared by the National Institute for Environmental Studies were determined by PIXE. The individual reference samples were analyzed in triplicate. Each sample pellet was irradiated for 15 min in a 5/8 inch diameter beam of 2.5 MeV protons. The X-ray measurements of irradiated samples were performed with a Si(Li) detector. The application of PIXE to 7 NIES standards showed that accurate analysis is possible for P, S and Mn in various materials such as leaves, algae, sediments and particulates with an accuracy of 10% or less. Moreover, concentrations of another 20 elements were determined with an accuracy of 10 to 50%.
