Abstract

A laboratory experiment is described that involves the elemental analysis of apples by inductively coupled plasma–atomic emission spectroscopy (IICP–AES). The results of the experiment allow students to predict the cold-storage stability of apples. During the experiment the sample-preparation techniques and digestion procedures involved in elemental analysis of solid organic samples are introduced and the optimization of the ICP–AES is explored. The method detailed can easily be adapted for the analysis of a wider range of elements. The laboratory experiment may also be undertaken using atomic absorption spectroscopy (AAS) with only minor modifications in the sample-preparation procedure.
