“…At high metrological level this system aims at realising traceability of chemical measurement results to the SI units in Germany. 1,2) In order to achieve small combined uncertainties according to GUM 3) high purity metals are used. For the system of national standards in Germany two kinds of materials -type A and type B-are involved: Type B material, which is intended for matrix adaptation, will be certified for the absence of metallic impurities and is not of further relevance here.…”

The special importance of the analysis of non-metals in high purity metals, which will serve as national standards for elemental analysis in Germany, is illustrated for oxygen and nitrogen. The typical range of the mass fraction of oxygen and nitrogen in these materials is below 10 µg/g, often close to 1 µg/g. The two methods applied at BAM for these measurements are classical carrier gas hot extraction (HE) and carrier gas hot extraction after activation with photons (PAA-HE). The approach, the methods and their advantages and limitations are discussed. Comparative results from the measurement of oxygen and nitrogen in Cu, Fe, Ga, Pb, Sn and W are presented.

“…Calibration standard solutions were made by dissolution of stock solutions prepared of dissolved pure elements. The decomposition of the pure matrix elements by HNO 3 or mixtures of HNO 3 and HCl was carried out under clean air conditions, partly under filtered highly-pure argon gas, to avoid contamination. PFA was used as the vessel material, cleaned before using with diluted pure HNO 3 , and in some cases additionally by mixtures of HNO 3 and HCl, and by vapours of HNO 3 using a special steaming apparatus.…”

The Bundesanstalt fü r Materialforschung und -prü fung (Federal Institute for Materials Research and Testing) (BAM) is establishing a system of primary reference materials to meet the demands for metrological traceability and to act as national standards in the field of elemental analysis. For all elements of the periodic table -except those that are gases or radioactive -two different kinds of reference materials are being certified. One is for analyte calibration (Type A) and one for problems concerning matrix matching (Type B). These substances are of very high purity and of defined stoichiometry. As far as possible, pure elements and metals rather than pure compounds are used. The certification of both types of material requires most elements of the periodic table to be certified at very low levels using trace element analysis methods. The application of these methods is described and examples of the certification of copper and iron are given.

“…9) Some authors have applied the method by using pressed pellets as samples for the analysis of geological 10,11) or organic material. 12) Regarding ultra pure metals the method has been applied successfully in case of ultra pure copper 4) and it will be tested and applied for other materials too. In the following section some experimental details are presented concerning the calibration of the analytical procedure (LA ICP MS) applied to the analysis of a high-purity copper material.…”

The Bundesanstalt für Materialforschung und -prüfung, BAM (Federal Institute for Materials Research and Testing) continues to establish a system of primary reference materials to meet the demands of metrological traceability. The materials act as national standards in the field of elemental analysis. For all elements of the periodic table-excepting those that are gases or radioactive-two different kinds of reference materials are being certified. The substances are of very high purity and of defined stoichiometry. Pure elements and metals are used as far as possible. They are certified by determining the trace contents of most elements of the periodic table at very low levels using different trace element analysis methods. Recent application of these methods is described and examples of the certification of some pure metals (copper, iron and lead) are given.
