Speciation of arsenic in fish products by LC-ICP/MS

While many elements are considered essential to human health, others can be toxic. However, because the intake, accumulation, transport, storage and interaction of these different metals and metalloids in nature is strongly influenced by their specific elemental form, complete characterization of the element is essential when assessing its benefits and/or risks. This is why, elemental speciation, which typically involves the coupling of a separation technique to a specific detector, represents the technique of choice to determine the different forms of an element.
