In analytical chemistry, a "mull" is a specialized preparation method used to obtain Infrared (IR) spectra of solid samples.
The technique involves grinding a solid sample with a heavy oil (typically Nujol ) to create a thick paste, which is then squeezed between salt plates.
Mull is famous for its complex Tertiary volcanic history, making it a "natural laboratory" for geologists.
