Certified reference materials (CRMs) from various producers are commonly used in trace analysis for method development and quality control purposes. Analytical techniques are becoming more and more sensitive and require smaller amounts of sample. Particularly, the so-called microanalytical techniques such as microproton-induced X-ray emission ({mu}-PIXE), laser ablation mass spectroscopy, solid sampling atomic absorption spectroscopy (AAS) or X-ray fluorescence techniques, etc., have increased demands on sample homogeneity. Determinations rely in some cases almost entirely on the availability of reference materials of proven homogeneity in the range of milligrams or below. This report describes the microanalysis of trace amounts in algae samples and an urban dusts. The repeatability of successive measurements was evaluated to compare relative homogeneity factors for as many as possible elements in the materials.
