Reference Standards are reliable, well-documented materials used in scientific research to ensure measurements are accurate and experiments can be trusted. Think of them like a trusted ruler that everyone agrees on - they help scientists make sure their results are correct and can be compared with other research. These could be pure chemicals, certified materials, or established procedures that serve as a baseline for comparing test results. Scientists use these standards to calibrate their equipment and validate their methods, much like how a scale needs to be zeroed before weighing something.
