Ultratrace 2 - Aqua Regia - ICP and ICP/MS

A 0.5 g sample is digested in aqua regia at 90 °C in a microprocessor controlled digestion block for 2 hours. The solution is diluted and analyzed by ICP/MS using a Perkin Elmer SCIEX ELAN 6000, 6100 or 9000 ICP/MS. One blank is run for every 68 samples. An in-house control is run every 33 samples. Digested standards are run every 68 samples. After every 15 samples, a digestion duplicate is analyzed. Instrument is recalibrated every 68 samples.

 

Certain elements (Ti, P and S) are analyzed by ICP/OES using a Varian 735 ES. This extends the dynamic range for a number of elements as well. International certified reference materials USGS GXR-1, GXR-2, GXR-4 and GXR-6 are analyzed at the beginning and end of each batch of samples. Internal control standards are analyzed every 10 samples and a duplicate is run for every 10 samples. This digestion is not total and will not dissolve silicates some oxides and resistate minerals (e.g., zircon, monazite, sphene, etc.).

Notes:

Au is semi-quantitative due to the small sample size.      
Extraction of each element by Aqua Regia Digestion is dependent on mineralogy. 

Unaltered silicates and resistate minerals may not be dissolved.
