RE: Big Question I need Answer The answer is graphite and is proven by the analytic procedure used by the lab:
Graphite assays were obtained using the graphitic carbon by LECO method (ALS protocol C-IR18). A 0.1-gram sample is leached with dilute hydrochloric acid to remove inorganic carbon (carbonate). After filtering, washing and drying, the remaining sample residue is roasted at 425 C to remove any organic carbon. The roasted residue is finally analyzed for graphitic carbon using a high-temperature LECO furnace with infrared detection. The samples were submitted with blanks and certified custom standards inserted into the sample stream to ensure lab integrity.
