Metrological concepts for enhancing the reliability of food and nutritional measurements

Metrology is a specialized discipline that deals with the science of measurements, irrespective of the field of application and regardless of the size of the measurement uncertainty. Incorporating metrological approaches into the measurement process enhances the reliability of analytical findings. These developments include: high-quality reference standards, validated methods, robust sampling practices, proven calibration approaches, natural matrix reference materials, speciation chemistry, assessment of measurement uncertainty and establishment of traceability links, certified reference materials to facilitate one aspect of traceability, and proficiency testing, among others.
