Elemental analysis of food substances presents a challenge because of the wide variety of food types and range of concentrations that need to be analyzed. This article discusses the analysis of a variety of food matrices with a single digestion procedure and instrumental method.

The potential for signal drift, matrix suppression, and spectral interference, in addition to demanding sample preparation, can make geological matrices some of the most difficult to analyze by conventional inductively coupled plasma-mass spectrometry.
