4 ACID

Keyword Definition

4 acid (hydrochloric (HCl), nitric (HNO3), perchloric (HClO4), hydrofluoric (HF)) digestion.  A “near-total” digestion, but will still not dissolve very resistate phases like chromite (FeCr2O4), barite (BaSO4), monazite ((Ce,La,Pr,Nd,Th,Y)PO4), sphene (CaTiSiO5), xenotime (YPO4), rutile (TiO2), etc.
