Reference Standard
A Reference Standard is a highly pure substance or precisely prepared solution used in laboratory testing to ensure accuracy of test results. Think of it like a "perfect ruler" that labs use to measure and compare their test samples against. When someone mentions working with Reference Standards in their resume, they're talking about using these benchmark materials to make sure laboratory tests are giving correct results. This is especially important in industries like pharmaceutical testing, food safety, and environmental analysis, where accuracy is crucial.
