Laboratory Number 1650052
Description 60 samples were prepped by dry sieve -150 mesh, crushed and split, and ceramic pulverizing. 60 samples were analyzed by the following methods and digestions: INAA, ICP after HF-HNO3-HClO4 acid digestion with HCl leach, AA after HCl:HNO3 (3:1) acid digestion, CVAA after HCl:HNO3 (3:1) acid digestion and XRF. Sn interference noted due to Sb. For Neutron Activation results, some samples have elevated lower detection limits due to high As and Sb. For sample 92JK36, results are semi-quantitative due to very, very high Sb. Iron results listed as over the limit may be equal to or over the detection limit for that analysis method.

Description 29 samples were prepped by crushing and pulverizing. 29 samples were analyzed by the following methods and digestions: titrimetric analysis and gravimetric analysis. 29 samples were analyzed for major oxides by XRF after lithium tetraborate fusion. 29 samples were analyzed for trace elements by XRF after pressed pellet preparation. Fe2O3 % is calculated.
