"Near Total" (4-Acid Digestion)

This digestion is as total as an acid digestion can get but will still not dissolve very resistate phases like chromite, barite, monazite, sphene, xenotime, etc. The digestion uses nitric, perchloric, hydrofluoric and hydrochloric acids with temperatures to 260 degrees C. The method is NOT suitable for rare earth elements. This digestion is used for Cu, Ni, Co, Pb, Zn, Mo and Ag assays.
