ABSTRACT:
A method and apparatus are provided for obtaining a reproducible sample of solid particles. The reproducible sample is obtained by receiving solid particles into a collection system that includes a sheltered volume. Solid particles that settle outside of the sheltered volume are purged from the collection system. The remaining solid particles inside the sheltered volume correspond to the reproducible sample.
