How does Thermo Fisher Scientific's analytical software support the calculation of measurement uncertainty? Wilhelm Sanders: According to DIN EN ISO 17025, it is necessary to calculate the measurement ...

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 ...

GUM, the internationally approved technique for calculating measurement uncertainty, is reliant on the availability of a certified reference sample. Likewise, to find any repeatable offset (systematic ...

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 ...

In the test and measurement industry, two distinct camps exist: those who favor vector network analyzers (VNA) and those who favor time domain reflectometers (TDR). Each camp relies heavily upon its ...

In order to use the result of a chemical analysis for other purposes, its quality must be assessed. One important quality feature is the probability that the result coincides with the ‘true’ value. It ...

Measurement uncertainty is a critical parameter that reflects the degree of confidence in the results provided by analytical and clinical laboratories. It encompasses the evaluation of both random ...

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.

When COVID-19 arrived, researchers tried to build evolutionary family trees—known as phylogenetic trees—of the virus. These ...

In the world of business and economics, there’s a bit of a fixation on uncertainty. To start, there’s the VIX, a measure of investor fear, that tracks expected volatility in the markets. But there’s ...
