It is now possible to carry out assessments automatically in minutes, guaranteeing consistency in testing from checking quality of trade goods and confirming the accuracy of doping tests on athletes to enabling tougher environmental legislation.
Knowing the real value of measurements is key to open trade and to effective legislation. But, the 25,000 public and private control laboratories around the world must take the same approach to checking values in areas from testing and calibration to food and pharmaceutical quality, environmental control and sports medicine. Knowledge of the uncertainty in results is a precondition for correctly assessing measurements accuracy.
To meet these demands, the International Standards Organisation (ISO) launched its Guide to the expression of uncertainty in measurements (GUM) in 1995. This is applicable to all levels of accuracy in all fields but addresses physical quantities. The European analytical chemistry association Eurachem produced its own guide – Quantifying uncertainty in chemistry – that translates GUM for chemical measurements in areas such as manufacturing quality control, regulatory compliance, calibration of standards and equipment, and certification of reference materials, as well as research and development.
However, these guides tend to be theoretical and time consuming. “We needed software to remove the barriers,” explains Dr Bruno Wampfler of the Swiss federal materials science and technology research institute (EMPA), coordinator of UNCERTAINTY MANAGER. This EUREKA project brought together testing laboratories, IT specialists and research centres in Austria, Germany and Switzerland to automate the process. Unlike other available techniques, UNCERTAINTY MANAGER offers unique benefits, not least fully automated evaluation, a large reference database and a powerful reporting tool.
“The reputation of the EUREKA label enabled us to obtain industrial participation in this project and is helping us to gain valuable visibility for the results,” adds Dr Wampfler. The software is already being made available through project partner VWR International, with continuing technical support from EMPA.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
