Speciation analysis is defined as the separation and quantification of different oxidation states or chemical forms of a particular element.
Elemental speciation is important in many application areas and is
becoming particularly important in the environmental, food, and
clinical industries.
the determination of total element concentrations alone cannot provide an adequate representation for clinical and environmental considerations in test sample.
In addition, its toxicity is not only linked to total concentration
but is also dependent on the species
.
