Preparation of Food Samples Using Homogenization and Microwave-Assisted Wet Acid Digestion for Multi-Element Determination with ICP-MS

Matjaž Rantaša¹, David Majer¹, Matjaž Finšgar¹

¹Faculty of Chemistry and Chemical Engineering, University of Maribor

The presented protocol describes sample homogenization with a laboratory mixer, acid digestion of food samples using a mixture of 68 wt% HNO₃ and 30 wt% H₂O₂ via microwave-assisted wet acid digestion, and multi-element determination performed with inductively coupled plasma mass spectrometry.
