Inductively coupled plasma-mass spectrometry (ICP-MS) for the analysis of trace element contaminants in foods

  • Helen M. Crews

Summary

This chapter describes the inductively coupled plasma, its interface to the mass spectrometer and the advantages and disadvantages of inductively coupled plasma-mass spectrometry (ICP-MS). Examples are given of applications in food analysis for single- and multi-element determinations, isotopic measurements and speciation studies. The applications are not restricted to contaminating elements such as arsenic, cadmium, mercury and lead, since the multi-element nature of the technique enables the analyst to measure a range of elements in a sample, including both toxic and nutritional elements, which may or may not be present as contaminants. Future prospects and requirements are considered.
