Heute werden eine Vielzahl von Referenzmaterialien aus den Gebieten Eisen/Stahl, Nichteisenmetalle, Keramik, Glas und Umwelt bereitgestellt. Im Vortrag werden die einzelnen Schritte der Referenzmaterialherstellung wie Probenpräparation, Homogenitätsuntersuchung und Zertifizierungsringversuch vorgestellt. Darüber hinaus werden Fragen der Zertifizierungsstrategie und Rückführbarkeit diskutiert.

This pilot study P76 was organized as an activity of the Inorganic Analysis Working Group of CCQM and was piloted by the Federal Institute for Materials Research and Testing (BAM). In total 12 laboratories (four NMIs and eight outside labs) submitted results, some of them more than one set of results per element. The laboratories were free to choose any analytical method they wanted to use for the analysis. Consequently various methods of measurement were employed: inductively coupled plasma optical emission spectrometry (ICP–OES), inductively coupled plasma mass spectrometry (ICP–MS), instrumental neutron-activation analysis (INAA), titrimetry, flame atomic-absorption spectrometry (FAAS), spectrophotometry (MAS), electrogravimetry, and gravimetric analysis. After testing for homogeneity within BAM, a certified reference material of lead-containing brass was used as test sample without informing the participants about the source of the material. The agreement of the results for all elements investigated was acceptable and mean values calculated from the results of all participants were close to the certified mass fractions of the CRM used as test sample. No statistically significant differences between the results of the NMIs and those of the non-NMIs could be observed.

This interlaboratory comité consultatif pour la quantité de matière key comparison (CCQM-K42) was organised as an activity of the Inorganic Analytical Working Group of CCQM. In total seven laboratories participated, six of them for all analytes. Measurands were the mass fractions of the analytes in a range of 0.05 and 0.2%. As an outcome the consistency of the results for all elements investigated was acceptable, hence satisfactory comparability was established. An aluminium based certified reference material—undisclosed to the analysts which one it was—was used as test sample. For the purpose of this study homogeneity was tested at BAM. Each laboratory was free to choose any analytical method they wanted to use for the analysis. Consequently various methods of measurement were employed: instrumental neutron activation analysis, X-ray fluorescence spectrometry (XRF) using fused cast-bead method combined with reconstitution technique, inductively coupled plasma optical emission spectrometry (ICP OES) and inductively coupled plasma mass spectrometry. Metrological traceability of the measurement results to the SI unit had to be demonstrated. Therefore, methods such as spark OES or XRF (without fused cast-bead technique)—both of them being most important methods for the analysis of metals and alloys in industrial laboratories—could not be used in the frame of the key comparison.

In European Reference Material ERM®-EB504, a used cordierite-based car catalyst material, mass fractions of platinum, palladium and rhodium were certified. The raw material was milled, homogenised and annealed before analysis. Seventeen laboratories experienced in precious metals analysis participated in the certification interlaboratory comparison, most of them analysing with inductively coupled plasma optical emission spectrometry using different sample pretreatment techniques. Homogeneity testing was carried out using X-ray fluorescence spectrometry. The certified mass fractions of Pt, Pd and Rh and their expanded uncertainties (k = 2) in ERM®-EB504 are (1777 ± 15), (279 ± 6) and (338 ± 4) mg/kg respectively.

Although the ISO-Guides related to CRM production and certification are not fully clear concerning calibration, many established CRM-producers do not accept matrix-CRMs for calibration in case of certification analyses, e.g. to avoid circular reasoning. These requirements limit the methods used for certification to those that can be calibrated using Standards of known high purity and stoichiometry or mixtures of such Standards. Powerful solid sampling techniques such as glow discharge mass spectrometry (GD-MS) or spark-optical emission spectrometry (SOES), where usually compact CRMs are used for calibration, seem not be applicable for certification analyses. Especially GD-MS is a powerful tool for trace element determination of solid samples. Beside metallic impurities the use of specific gas mixtures enables also the determination of interesting nonmetallic impurities such as sulfur and phosphorus. Within BAM a calibration approach, was developed which enables to use mixtures of Standards of known high purity and stoichiometry also for GD-MS. Analogue to matrix adaption in solution based techniques, the calibration approach is based on doped pressed powder pellets. Approach and application on the certification analyses of copper and Steel CRMs are presented.

Dazu bieten sich im Prinzip zwei Wege an: 1. Verwendung von Primärnormalen zur Kalibrierung oder von Primärmethoden, 2. Verwendung von zertifizierten Referenzmaterialien. Die Verwendung von zertifizierten Referenzmaterialien (ZRM) setzt voraus, dass diesen ZRM ein (oder mehrere) auf SI rückführbarer zertifizierter Wert (z.B. Massenanteil) mit dazugehöriger Unsicherheit zugewiesen wurde. Ein möglicher Weg, dies zu erreichen, der von BAM und EMPA in Zusammenarbeit mit der Fa. Fluka für Kalibrierstandards (Anionen- und Kationenlösungen, Urtitersubstanzen) beschritten wurde, wird hier beschrieben. Zertifiziert wurden - Kationen-Standardlösungen (1000 mg/L) für Spektrometrie - Anionen-Standardlösungen (1000 mg/kg) für Ionenchromatographie - Urtitersubstanzen (> 99,5 %) für Titrimetrie Die Materialien wurden bei Fluka hergestellt, die Überprüfung der Homogenität der abgefüllten Charge erfolgte bei der EMPA. SI-rückführbare Zertifizierungsanalysen wurden in der EMPA sowie in der BAM mit zwei unterschiedlichen analytischen Methoden durchgeführt. Dabei kamen neben spektrometrischen und chromatographischen Verfahren auch klassische Methoden wie Titrimetrie und in Einzelfällen Gravimetrie zum Einsatz. An ausgewählten Beispielen werden Messverfahren, Berechnung der Messunsicherheit und Rückführung auf SI gezeigt.

The latter is especially meaningful in European Union and other countries where strict legislations on GMOs were set up. Performance of the methods used in laboratories around the world should be uniform, in order to obtain reliable and comparable results. Accreditation is a suitable system for harmonising procedures in each testing laboratory. In this paper, key elements for the accreditation of molecular biology methods for GMO detection according to ISO/IEC 17025 are described. The procedures described are also valuable for the accreditation of molecular methods for all laboratory diagnostics where qualitative and quantitative characterisation of nucleic acids is needed.

Elements to be analysed were Cr, Mn, Ni and Mo in low alloy steel. The National Metrology Institute of Japan (NMIJ), the National Institute of Standards and Technology (NIST) and the Federal Institute for Materials Research and Testing (BAM) acted as the coordinating laboratories. The participants used various measurement methods, though many of them used ICP-AES. Generally speaking, the agreement of the results was very good for each measurand.
