Prioritizing Purity: How Pure is Pure Enough?
Purity is often viewed through the lens of the application or the chemist using a material. One level of purity can be good for a specific application and fail in another situation, making it a very relative benchmark. In this paper, we will discuss the importance of defining purity, impurities, and the situations in which high-purity inorganic raw materials are essential for analytical success.
