ABSTRACT:
The material composition of geological samples is
very complicated. Generally, the method for accurately determining trace
elements in geological samples needs to digest the solid samples into liquid
state, which is convenient for inductively coupled plasma mass spectrometry.
The previous digestion method takes a long time and the operation process is
complicated. The Ultra CLAVE microwave
digestion instrument was used to digest the geological samples. The types and
dosages of the acid used for digestion and the optimal conditions for
instrumental testing were published. The results show that this method has
short processing time, small data error, safer operation and good digestion
effect. This method is suitable for geological sample analysis.
