Chemex ICP-AES (Hg ppm) (32 elements)



Inductively coupled plasma–atomic emission spectroscopy analysis of 32 trace elements was performed.  These analyses were done by Chemex Labs Ltd., in Mississauga, Ontario.

Hg is reported in ppm.

General Methodology:

Geochemical composition of samples was determined by inductively coupled plasma / atomic emission spectroscopy. The ICP analysis was performed by Chemex labs Ltd., Mississauga, Ontario for 32 trace elements. Two grain size fractions (clay and silt plus clay) were analyzed separately, because trace metals tend to concentrate in the clay fractions. In the ICP-32 analysis a 1.0g aliquot was digested using a concentrated nitric-aqua regia solution for two hours. The nitric aqua-regia digestion may only be partially complete for the following elements: Al, Ba, Be, Ca, Cr, Ga, K, L, Mg, Na, Sr, Ti, Tl, and W. The solution was then diluted to 25 ml with demineralized water and analyzed with a Jarrell Ash 1100 plasma spectrometer.
