Trace Metal Speciation

Speciation Analysis

Speciation concerns the identification and quantitation of specific forms of an element, e.g. the analysis of edible fish tissue to determine the concentrations of methylmercury and inorganic mercury present. As different forms of an element may exhibit differing toxicities and mobilities in the environment, it is clearly of importance to be able to distinguish between the individual species present in a particular sample.

As is generally the case in analytical chemistry, speciation analysis requires a multi-step approach, typically including the following operations:-
