Blanks in Method Validation - Eurachem

A reagent blank is a mixture of any solvent(s) and/or reagent(s) that would be presented to the detector for analysis of a test sample and is analysed to determine if it contributes to the measurement signal. Reagent blanks are often used with techniques such as …

Metrological Traceability in Chemical Measurement

Measurement underpins a wide range of socio-economic activities, both domestic and international. Every day, thousands of chemical measurements support decisions on food safety, health and environmental protection. The global market, too, needs accurate and reliable measurements so that technical barriers to trade can be minimised.

The bias component in measurement uncertainty - Eurachem

3.2.7. In carrying out studies of overall bias, it is important that the reference materials and values are relevant to the materials under routine test. 5.4 …method used is empirical. It is not meaningful to consider correction for bias intrinsic to the method, since the measurand is defined by the method used. 6.6. In practice, it is more ...

The SI defines the second based on a property of the cesium atom, and for this reason, cesium oscillators are regarded as primary standards for both time interval and frequency. A second is defined as the time interval required for 9 192 631 770 transitions between two energy states of the cesium atom to take place.
