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 ...

Accuracy is a desirable aspect which is conceptually well defined. There are some definitions available for ‘accurate measurement’ in the ISO vocabulary of metrology terms. According to them, a ...

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 ...

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 ...

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.

For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope revealed Jupiter’s moons and shook the geocentric universe. Thomas Young’s ...

Scientists report the first direct real-time measurement and control of quantum uncertainty dynamics using ultrafast squeezed ...

By using something called a quantum grid, scientists have found a clever way to simultaneously measure momentum and position ...
