6.3.      Microwave Digestion System

MARS 6 - Microwave Digestion System

Microwave digestion is an established technique that has been used for many years. Sample digestions are used to suspend samples in the liquid phase, as this facilitates trace metal analysis. Using a microwave digestion method provides two main benefits: Firstly, using microwave energy in a sealed vessel significantly increases the boiling point of an acid. This extra temperature means samples can be digested faster and more effectively. The other advantage is that it is impossible to completely digest some types of materials using just acids at atmospheric boiling points. In order to digest these types of materials, a higher temperature is necessary. Using the sealed container, as in microwave digestions, this is possible.
