Good sample preparation is essential for performing high-quality chemical analysis using X-ray fluorescence (XRF). Whichever samples are being assessed – loose or pressed powders, fused beads, solid samples or liquids – finding the right approach to sample preparation for XRF is the first, and one of the most important, steps in achieving accurate and reproducible results.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Metallography; Metallography. Metallography is the most reliable way of identifying the structure of a given product. Through processes such as cutting, mounting, grinding and polishing, a smooth specimen surface is obtained. The purpose for sample preparation is to obtain the material''s true structure, without deformation of any kind.
