Ultratrace 1 - Aqua Regia - ICP/MS

A 0.5 g sample is digested in aqua regia at 90 °C in a microprocessor controlled digestion block for 2 hours. Digested samples are diluted and analyzed by 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.

Notes:     

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

U naltered silicates and resistate minerals may not be dissolved.

+ Sulphide sulphur and soluble sulphides are extracted.
