Whether focusing on the essential or functional food components
of food products, there is a need for accurate, reliable, and
convenient methods of measuring the essential mineral composition
of food matrices, in order to satisfy the analytical requirements
of product development, quality control, and food
regulatory authorities. Atomic absorption spectrometry has long
been a standard technique for measurement of single elements.
On the other hand, optical emission spectrometry (OES), also
known as atomic emission spectrometry, allows sensitive multielement
analysis because characteristic emission spectra may be
generated for a range of elements under the same excitation
