Intercomparison of techniques available at INETI in the analysis of two IAEA candidate research materials.
Under contract with the IAEA, the epiphytic lichen Evernia prunastri was collected to prepare a multielement lichen reference material for quality assurance of environmental studies. An intercomparison run on trace and minor elements in this candidate research material (IAEA-336) was organized in which six analytical groups of the National Institute of Engineering and Industrial Technology (INETI) took part. INAA, PIXE, XRF, AAS, and ICP-ES were applied. The results obtained by different methods are compared, and their complementarity is discussed. As a quality control, the IAEA cabbage research material (IAEA-359) was analyzed. The results agree quite well with the estimated values given by the IAEA.
