Abstract
Mineral samples for use in analytical instruments are created by a system that greatly reduces the sample preparation time and facilitates automation. For example, in some implementations, rather than grinding to expose the interior of mineral particles in sample plug containing mineral particles in an epoxy compound, the sample plug is sliced with a saw, which more rapidly provides in many applications a sufficiently smooth surface on the exposed particle surfaces for observation. Rather than slowly mixing a slow curing epoxy to avoid introducing bubbles into the sample plug, some implementations use a fast settle fixative and a mechanical mixture that avoid bubbles.
