8 - Coal Package

FUS-ICP + ICP-MS
A lithium metaborate/tetraborate fusion ICP whole rock analysis.  A fused sample is diluted and analyzed by Perkin Elmer Sciex ELAN 6000, 6100 or 9000 ICP-MS. Three blanks and five controls (three before sample group and two after) are analyzed per group of samples. Duplicates are fused and analyzed every 15 samples. Instrument is recalibrated every 40 samples.

INAA
A 1- 30 g sample is analyzed by INAA.  INAA is an analytical technique dependent on measuring gamma radiation induced in the sample by irradiation with neutrons. The primary source of neutrons for irradiation is usually a nuclear reactor. Each activated element emits a "fingerprint" of gamma radiation which can be measured and quantified. 

"Near Total" Digestion - ICP Portion
A 0.25 g sample is digested with four acids beginning with hydrofluoric, followed by a mixture of nitric and perchloric acids. This is then heated using precise programmer controlled heating in several ramping and holding cycles which takes the samples to incipient dryness. After incipient dryness is attained, samples are brought back into solution using aqua regia.

Notes:       
Extraction of each element by 4-Acid Digestion is dependent on mineralogy.
 
+ Sulphide sulphur and soluble sulphates are extracted.
