T1 - Final report of the key coamparison CCQM-K88: Determination of lead in lead-free solder containing silver and copper N2 - The CCQM-K88 key comparison was organized by the Inorganic Analysis Working Group of CCQM to test the abilities of the national metrology institutes to measure the mass fraction of lead in lead-free solder containing silver and copper. National Metrology Institute of Japan (NMIJ), National Institute of Metrology of China (NIM) and Korea Research Institute of Standards and Science (KRISS) acted as the coordinating laboratories. The participants used different measurement methods, though most of them used inductively coupled plasma optical emission spectrometry (ICP-OES) or isotope-dilution inductively coupled plasma mass spectrometry (ID-ICP-MS). Accounting for relative expanded uncertainty, comparability of measurement results was successfully demonstrated by the participating NMIs for the measurement of the mass fraction of lead in lead-free solder at the level of 200 mg/kg. It is expected that metals at mass fractions greater than approximately 100 mg/kg in lead-free solder containing silver and copper can be determined by each participant using the same technique(s) employed for this key comparison to achieve similar uncertainties mentioned in the present report.

T1 - Certified reference material for determination of total cyanide in soil [BAM-U116/CGL306] N2 - CRM (Certified Reference Material) BAM-U116/CGL306 “Cyanide in soil” was produced within a framework of cooperation between CGL (Central Geological Laboratory) of Mongolia and Federal Institute for Materials Research and Testing (BAM) of Germany in 2013-2017. The CRM BAM-U116/CGL306 represents a mixture of a sandy soil collected from a contaminated former gasworks area in the Berlin region (Germany) and an unpolluted sandy soil from Nalaikh region (Mongolia). The bulk candidate material for this reference material was prepared at CGL CRM Laboratory exclusively destined to the preparation of reference materials and equipped with modern technical equipment. Homogeneity, stability and shelf life were studied in full compliance with ISO Guide 35. The CRM was evaluated as sufficiently homogeneous. Statistical evaluation of certification analysis was software packages SoftCRM and ProLab Plus. Certified value of total cyanide of the CRM is 12.0 mg/kg and expanded uncertainty was assigned as 0.8 mg/kg. The intended purpose of this material is the verification of analytical results obtained for the mass fraction of total cyanide in soils and soil-like materials applying the standardized procedure ISO 11262:2011. As any reference material, it can also be used for routine performance checks (quality control charts) or validation studies.

A1 - Recknagel, Sebastian T1 - Quecksilber-, Cadmium- und Bleigehalte in Gerätebatterien im Lichte der rechtlichen Entwicklungen N2 - Für die Schwermetalle Quecksilber, Cadmium und Blei gibt es aufgrund ihrer Gefährlichkeit gesetzliche Vorgaben für ihre Gehalte beziehungsweise ihre Kennzeichnung in Gerätebatterien. Die Bundesanstalt für Materialforschung und -prüfung hatte im Jahr 2006 rund 140 Gerätebatterien auf ihre Gehalte an diesen drei Metallen analysiert. Nachdem mit dem Batteriegesetz im Jahr 2009 die Grenz- beziehungsweise Schwellenwerte verschärft worden waren, wurde im Jahr 2011 erneut eine Stichprobe von 146 Gerätebatterien - Knopfzellen, Rundzellen, Akkus für Mobiltelefone und 9V-Zink-Kohle-Blöcke verschiedener chemischer Systeme und Hersteller - analysiert. Für die Analysen wurden die Knopfzellen vollständig in Säure aufgelöst, die anderen Batterietypen wurden zunächst mechanisch in ihre Fraktionen zerlegt. Zur Bestimmung der Elemente kamen ICP-MS, Kaltdampf-AAS, ICP-OES und ein automatischer Quecksilberanalysator zur Anwendung. Ergebnisse: Die Schwermetallniveaus änderten sich zwischen 2006 und 2011 insgesamt wenig. Die untersuchten AlMn-Rundzellen und Li-Ion-Akkumulatoren für Mobiltelefone enthielten 2011 die durchschnittlich geringsten Schwermetallgehalte, während die Zink-Kohle-Rundzellen durchschnittlich am stärksten belastet waren, maximal mit 41,4 mg/kg Quecksilber, 170 mg/kg Cadmium beziehungsweise 1958 mg/kg Blei. Außerdem fehlte auf der Hälfte der Batterien die erforderliche Element-Kennzeichnung mit 'Hg' beziehungsweise 'Pb'.

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.
