KBr pellets

KBr pellets are small discs made from potassium bromide, a chemical that is often used in infrared spectroscopy, a technique for identifying materials based on how they absorb light. To create these pellets, KBr powder is mixed with a sample and compressed into a disc form. This process allows the sample to be analyzed effectively, as the KBr is transparent to infrared light. Using KBr pellets is a common method in laboratories because it provides clear spectra, helping scientists study the composition and characteristics of various substances.
