Measurement uncertainty, as described in ISO/IEC Guide 98, is a “parameter, associated with the result of a measurement, [which] characterizes the dispersion of values that could reasonably be ...

Precision can be defined as the closeness in agreement of results during a series of repeat measurements under presumed identical conditions. These results are often expressed as a standard deviation.

Measurement uncertainty represents a fundamental parameter in analytical chemistry, encapsulating the range within which the true value of a measurement is expected to lie. This concept is integral to ...

Based on the EURAMET Calibration Guide No. 18 “Guidelines on the Calibration of Non-Automatic Weighing Instruments” 1–3 (represented as “EURAMET cg-18”), this QApp function offers a dynamic display of ...

Every year an increasing number of laboratories using OES (Optical Emission Spectroscopy) spectrometers get accredited according to DIN EN ISO 17025. Compliance with DIN EN ISO 17025 has elevated the ...

Scientists find a 'measure and remeasure' approach is a feasible method of verifying soil carbon storage in croplands for climate mitigation. Directly measuring soil carbon rather than relying on ...

The authors do not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and have disclosed no relevant affiliations beyond their ...

Quantum measurement and uncertainty relations lie at the heart of quantum mechanics, delineating fundamental limits on the precision with which non-commuting observables can be simultaneously ...

Scientific progress has been inseparable from better measurements. Before 1927, only human ingenuity seemed to limit how precisely we could measure things. Then Werner Heisenberg discovered that ...
