Cryogenic preparation of sample materials
24 Mar 2023Size reduction plays an important role in sample preparation as it has a substantial influence on the results of subsequent analyses. If particles are too coarse or inhomogeneous the results of the analysis can be incorrect. In this application note, explore how the range of laboratory mills from Retsch are suitable for cryogenic grinding and consider which mill is correct for specific workflows.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Mills, Sieves and PressesMills, sieves and presses are used to break and sort solid materials into smaller particle sizes for further processing such as pellet pressing or analysis. Milling equipment includes grinders, ball mills, cutting mills, jaw crushers, knife mills, beater and planetary mills. Sorting of smaller particulates can be achieved with test sieves and sieve shakers. Final powders can be pressed with hydraulic presses. Milling and pressing solid samples is an important preparation step in X-ray fluorescence spectroscopy (XRF) and diffraction (XRD).
