  Abstract:  This paper presents the comparison between two mineralization methods of some food product samples (dairy products): 1. acid digestion in open system with thermal heating; 2. microwave acid digestion in closed system, under controlled pressure. The analytical determination was realised with an atomic absorption spectrometer with flame and graphite furnace. There were marked out the advantages of the microwave digestion: analysis short time, minimal contamination of the sample, necessity of small quantities of the sample and reagents, minimal residual generation and the maintenance traceability of the results.

Keywords: wet digestion, microwaves, atomic absorption spectrometry
