Description
Several powder standard reference materials (SRM) used mainly in geological and environmental applications have been tested for reliability on milligram scale. Specific experimental conditions such as beam energy and diameter, as well as the matrix composition of the analysed samples, determine a lower limit on the necessary mass for which the SRM must be homogeneous. These mass limits have been determined for specific elements and are compared to the minimal mass required for analysis as specified by the certifying body. Since the accuracy of PIGE analysis is often hindered by the presence of interfering nuclear reactions, this narrows down the useful number of elements for which the SRM is certified. (author)
