| Popis: | Three very accurate (definitive) methods by RNAA for the determination of Se, As and Fe respectively, which were recently elaborated in our laboratory, are reviewed and their use in certification of reference materials and in checking the assigned values in proficiency tests is demonstrated on several examples. According to VIM 3 nomenclature these methods may be called: ratio primary reference measurement procedures (RPRMPs). RPRMPs with their expanded uncertainties of 2.7–3.6 % are comparable to ID-MS methods and are the only methods of such high metrological quality which can be used for the determination of trace amounts of monoisotopic elements. |
