Referanseringsprøver

Referanseringsprøver, also known as reference samples or standard samples, are materials used in analytical chemistry and related fields to calibrate instruments and validate analytical methods. They are characterized by a precisely known composition or property, established through rigorous testing. The purpose of using referanseringsprøver is to ensure the accuracy and reliability of measurements made on unknown samples. By comparing the measurement of an unknown sample to the measurement of a referanseringsprøve with a known value, analysts can determine the concentration or property of the unknown.

These samples are crucial for quality control in various industries, including pharmaceuticals, environmental monitoring, food safety, and materials science. For instance, in environmental testing, referanseringsprøver of water with known pollutant levels are used to calibrate equipment that measures contaminant concentrations in actual water samples. Similarly, in pharmaceutical manufacturing, reference standards of active ingredients ensure that drug dosages are consistent and accurate. The preparation and certification of referanseringsprøver are highly standardized processes to guarantee their traceability and reliability. Certified referanseringsprøver, often provided by national metrology institutes or accredited organizations, come with a certificate detailing their certified value, uncertainty, and the methods used for their characterization.
