Spectrometer samples need to be polished
Before analysing samples via microscopy or X-ray diffraction, it must be ensured that the sample surface is planar and completely cleaned. To ensure this, samples are ground and polished before characterisation. Unless your samples are properly prepared, you risk collecting misleading data that can compromise research projects, quality control practices, and analytical conclusions. Metallographic polishing, just like metallographic grinding, is the final stage in the sample preparation process of metals for subsequent analysis. These steps refine the surface of a specimen to remove deformation, scratches, and irregularities introduced during sectioning and mounting. A fine mechanical (or chemical) polish is required for specimens that will be analyzed using optical microscopy or certain SEM techniques (EDS elemental analysis and EBSD phase and orientation characterization in particular). A well-polished sample ensures: Accurate Analysis: Eliminates artifacts that can interfere with test results.
