• synchrotron radiation X-ray fluorescence
• particle induced X-ray emission
• micro-reference materials
• homogeneity test

The two micro-analysis techniques, synchrotron radiation X-ray fluorescence and macro-proton induced X-ray emission (macro-PIXE), were used in a homogeneity test of two candidate reference materials (RMs), lichen IAEA-338 and algae IAEA-413 (International Atomic Energy Agency, IAEA), in the present work. The two candidate RMs had good homogeneity with the minimum sampling mass of 10 mg required for micro-analytical nuclear techniques. The elemental content in the RMs was also determined by macro-PIXE. The relative homogeneity factors H-E of elements in the RMs were estimated on the base of our macro-PIXE results.
