The McCrone micronizing mill prepares samples for analysis by X-ray diffraction, X-ray fluorescence, infrared spectroscopy, and atomic absorption analysis. The sample goes in a jar that includes agate grinding elements, and the jar gets locked in the mill for a timed run. The longer the grind, the finer the sample.
