2E -Vegetation Ash for Au, Pt, Pd - ICP/MS

Samples are ashed at low temperature in dedicated ovens at 475 ° C for 24 hours. 0.25 g of ash is digested in aqua regia at 95 ° C for 2 hours.  Digested ash samples are diluted and analyzed by Perkin Elmer Sciex ELAN 6000, 6100 or 9000 ICP/MS. A blank is run every 69 samples. Two digested controls are analyzed every 69 samples. Duplicates are digested and analyzed every 14 samples. Instrument is recalibrated every 69 samples. Results are reported on an ash weight basis.  On request results can be computed on a dry weight basis.
