of a homogeneous, flat disk. Liquid samples, from water to oil, are run in sample cells covered with a thin film. Many solid samples, if homogeneous, can be machined to the proper shape and run directly. Others, such as refractories, ores, and biological materials, are too inhomogeneous and must be pulverized
