Decomposition in microwave oven - a pretreatment method for determination of elements using atomic spectrometric methods. Target group: M

The module is mainly aimed at students that will need to decompose samples before analyses using ICP-OES, ICP-MS or AAS.

Learning goal:

Be able to find the best conditions and perform decomposition of various materials in microwave oven as pre-treatment for determination of trace elements using atomic spectrometric methods.This involves knowledge of instrument (hardware and software of the microwave oven), operation principle, acid properties, safety aspects and quality control.
