Multi-acid digestion uses a combination of HCl (hydrochloric acid), HNO3 (nitric acid), HF (hydrofluoric acid) and HClO4 (perchloric acid). Because hydrofluoric acid dissolves silicate minerals, these digestions are often referred to as 'near-total digestions'.
Multi-acid (4 acid) digestion is a very effective dissolution procedure for multi-element analysis at trace levels of detection. However, there can be a loss of volatile elements (e.g. B, As, Pb, Ge, Sb) during this type of digestion and some refractory minerals (especially oxide minerals) are only partially digested. Our experts will help you select a method that is fit-for-purpose.
The following elements can be added to above package:Ce, Hf, Nb, Rb, Se, Te, Th, U
The following elements can be added to the above package: Dy, Er, Eu, Gd, Ho, Nd, Pr, Sm
