TEST Assay (By gravimetry, as palladium). Dry 0.4 g of sample at 110 °C for 2 h. Accurately weigh 0.3 g of the cooled and dried sample in a 250 mL beaker. Add 10 mL of 10% hydrochloric acid, and gently warm on a hot plate (~100 °C) to dissolve the sample. Dilute to 75 mL with water. Add 100 mL of 1% dimethylglyoxime reagent solution, heat on a hot plate for 1 h. Filter through fine-porosity ashless filter paper, and wash the precipitate with 50 mL of hot water. Carefully place the filter paper containing the precipitate in a preconditioned and tared porcelain crucible with lid. Heat in an oven for 1 h at 150 °C. Finally, ignite in a muffle furnace at 600 ± 25 °C for 15 min. Cool, and weigh. The weight of the precipitate should be within limits.
