Base metals and Multi-elements
Digestion A (4 acid)
Multi-acid attack including hydrofluoric, nitric, perchloric and hydrochloric acids in teflon beakers. Suitable for dissolving silica based samples requiring low levels of detection. This digest approaches total dissolution for most minerals. Elements incorporated in highly resistant mineral may not be dissolved in the four acid. These include, but are not limited to, columbite, tantalite, cassiterite, wolframite, spinels, some garnet species, rutile, zircon and ilmenite.
Digestion cost - $7.50 sample
Digestion AT
As for digestion A (above) but in teflon test tubes using our specially designed, microprocessor controlled digester. This option offers better control of the staged digestion process. Not suitable for lead or silver ores. Not used for samples prepared in zirconia mill. Germanium not available by this digest. Some minor chromium and antimony losses may occur.
Digestion cost - $6.00 sample
Digestion M (3 acid)
As for digestion A (above) but excluding hydrofluoric acid. Silica based minerals not dissolved.
This digest is not recommended for the lithophile elements
Digestion cost $7.00 sample
Digestion RA
Digestion RM
Digestion A or digestion M after pre-roast (ashing) to remove graphitic and other organic material. (NB some analytes may be lost during roasting.)
Digestion RA cost $14.00 sample
