7 - Mobile Ion Geochemistry

Mobile Ion Geochemistry isolates the chemically active metal ions which were loosely adsorbed to soil particles. This is a weak leach that uses a solution of organic and inorganic compounds to extract target elements.

 

The solutions are analyzed on a Perkin Elmer ELAN 6000, 6100 or 9000 ICP/MS.  One matrix blank is analyzed per 49 samples. Two controls are run at the beginning and end of the group of 49 samples. Duplicate samples are leached and run every 10 samples.
