Interest in Elemental Speciation Analysis â¢ Speciation analysis is the analytical activity of identifying and/or measuring the quantities of one or more individual chemical species in a sample. â The chemical species are specific forms of an element defined as to isotopic composition, electronic or oxidation state, and/or complex or molecular structure. â¢ Different forms of an element can have totally different properties. â Essential for predicting and modeling fate, risk, and effects, Critical for toxicology,
