Sample Preparation. Before you mount your sample in a sample holder, you should consider whether you need to grind or sieve it. Grinding (or even milling) may seem an obvious requirement if you want to achieve a fine powder. For some materials, e.g. many ceramic powders, grinding presents no problems and should always be performed.
