A sample which results where a small portion has been separated from the @L03630@ or @L03433@ by selective means such as magnetic-, density-, or manual separation, by @M03894@-drilling, or by centrifugation, e.g. the separation of magnetic materials from a geological material, or the separation of metal particles from a lubricating oil. If individual particles are analysed the term individual particle analysis is applied.
