Sample Preparation Most of the time, the samples are not analyzed directly "as it is", but a preparation is required. Depending of the analytical technique and the kind of samples, the preparation can be totally different. Usually, preparing a sample can be very long and the impact on the final result can be much more than the analyzer only.

After a metallographic sample has been mounted, grinding and polishing creates a flat and even surface. Any potential residue from the mounting process or damage from the sectioning process are ground off to expose the actual microstructure of the sample. Polishing removes abrasions from the previous steps to provide a smooth surface.
