Digested ash samples are diluted and analyzed by Perkin Elmer Sciex ELAN 6000, 6100 or 9000 ICP/MS.  A matrix blank and digested blank are each run every 35 samples.  Two digested standards are run every 35 samples. Instrument is recalibrated every 70 samples. Duplicates are digested and analyzed every 14 samples. Results are reported on an ash weight basis.  If Au, Pd, Pt are required please use Code 2E.
