Keeping track of evaporating solutions to maintain traceability
No full textStandard solutions are fundamental tools to guarantee traceability in chemical analysis, however, they might suffer solvent evaporation during long storage periods. In this work a measurement model is presented to consider this behaviour and assure the retention of metrological traceability by taking into account solvent evaporation through subsequent weightings at the start and end of the storage period. The proposed iterative formulation is tailored to suit three different experimental setups depending on the available information. Uncertainty budgets based on the proposed models were produced and filled with simulated data to test the contribution of parameters and increment to the combined variance. The results highlighted strengths and drawbacks for each approach but ultimately asserting their suitability within the testing conditions. General considerations were also drawn with recognition of the limitations of the proposed modelisation and the great importance reserved to the knowledge of matrix interactions
EMN-Q - Strategic Research Agenda and Quantum Technologies Roadmaps
Full text linkTogether with the EMN-Q web platform, EMN-Q events and workshops this Strategic Research Agendanrepresents, in the intention of the EMN-Q members, one of the main communication channels to QT stakeholders from academia, industry, and standardisation bodies.
The Strategic Research Agenda once developed will be periodically updated by the EMN-Q, with the
support of the QT community, to ensure that QT metrology needs, even if evolving, are taken into
account and national metrology activities are coordinated, prioritised and focussed. The roadmaps will ensure that NMIs can align their research programmes in anticipation of future needs so that European QTs will be supported far into the future. In turn, QT stakeholders will acquire confidence that their metrological needs will be addressed by a long-term and coherent approach; improving on the present situation where short-term projects are based on ad-hoc needs. NMIs' awareness and involvement early on in device development will provide assurances to the user community and help the QT market to grow
