The world depends on a collection of strange items. They're not cheap
The US government's National Institute of Standards and Technology (NIST) operates a large warehouse storing nearly 1300 "standard reference materials" (SRMs). These are not for general public use but are highly specialized items like extremely expensive jars of peanut butter, samples of sludge, or even a standard bullet. The purpose of these SRMs is to provide a "truth in a bottle"—a perfectly characterized sample of a substance with known quantities of its components. Researchers and manufacturers buy these SRMs to calibrate their equipment, ensuring that their measurements of various products, from food nutrients to steel strength and even environmental contaminants, are accurate and reliable. This work is crucial for product safety, quality control, and ensuring consistency across industries, helping to ensure that products meet their stated specifications and that tests for harmful substances are precise.
