Summary

Rare earth element analysis on 5 gram vial samples for analysis by Instrumental Neutron Activation Analysis. For Ba, Sn, and W, a 10 gram pressed pellet was prepared for analysis by X-Ray Fluorescence. A 30 gram sample of gold was pre-concentrated by fire assay and finished with Atomic Absorption Spectroscopy. Platinum and palladium were analyzed by fire assay pre-concentration of a 30 gram sample and an ICP finish. Mercury was analyzed by cold vapor AA methods. All other trace elements were 0.5 gram samples dissolved in aqua regia for analysis by Inductively Coupled Plasma Spectroscopy or Atomic Absorption Spectroscopy. Samples above the detection limits for gold, were reanalyzed with a Gravimetric finish. Sample that exceeded the [...]
