Acid Digestion

What is microwave acid digestion?

Microwave Digestion is a common technique used to dissolve metals into an aqueous solution prior to elemental analysis. The process involves irradiating a sample in strong acids in a sealed vessel which raises the boiling point of the acid, creating a super acid. This super acid, or combination of acids, increases the speed of decomposition as well as the solubility of metals in solution. Once they are in solution, it is possible to quantify the samples for trace metal analysis.

Suitable for:

  • ICP-MS
  • AA
  • GFAA
