Round Robin Exercise #18,
Raw Spent Petro-catalyst
Alumina based, Platinum

This bulk sample was prepared by Josh Husvar of Cotecna. Josh personally documented the bulk sampling process for this material and will be presenting on it at the June conference. In the meantime this is being distributed as the next round robin. Keep in mind this sample is in the raw unprocessed form and will need processing before analysis. As part of the report we are asking you to share what methods you used to prepare the material for analysis.

The final results round robin exercise will be correlated to the presentation Josh will give. Should be interesting!
