Stable isotope analysis gives an independent measure of fractionation such that if, for instance, a sample is 1.5% heavier in 13C than modern standard carbon through the effects of fractionation, then it will be 3% heavier in 14C than it would have been had fractionation not taken place.
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, bioavailability, and bioaccumulation. â In fact, speciation of an element can even impact total elemental analysis. â¢ Speciation Analysis Can Answer Tough Questions
