Standardreferenz

A Standardreferenz, often translated as standard reference or reference standard, is a highly purified substance used as a benchmark in analytical chemistry and other scientific disciplines. Its primary purpose is to provide a basis for comparison when analyzing unknown samples. A Standardreferenz possesses precisely known characteristics, such as purity, concentration, or activity.

In analytical testing, a Standardreferenz is used to calibrate instruments, validate methods, and quantify the presence of specific substances in a sample. For example, in pharmaceutical analysis, a Standardreferenz of a drug is used to determine the exact amount of that drug present in a manufactured tablet. Similarly, in environmental testing, a Standardreferenz for a pollutant allows scientists to measure its concentration in water or air samples accurately.

The production and certification of Standardreferenz involve rigorous procedures to ensure their reliability and consistency. These standards are typically produced by specialized organizations or laboratories that adhere to strict quality control protocols. Their availability and use are crucial for ensuring the accuracy, comparability, and traceability of scientific measurements across different laboratories and over time, contributing to quality assurance and regulatory compliance.
