Comments; Fer all obviously heterogeneous samples easily separated irrto subsamples, and for layered samples, each component is analyzed separately. Also, "# qt Layers" refers to number of separable subsamples. • NV samples analyzed by ELAP 198.1 Method.

Note: ’"Two samples were submitted with I050-2B-002. both results given.
