Extract:

Many governing bodies now recognize that some elemental species rather than the total elemental concentration should be controlled. Toxic species, such as methylmercury and organotins have generated much interest over recent years with efforts to understand their reactivity and mobility in the environment. Subsequently, the recognition of the acute toxicity of these species has led to their inclusion in future amendments to the EU Water Framework Directive (WFD) which will impose ppt limits of mercury species and sub-ppt limits for tributyltin compounds as annual average concentrations in inland waters.

To address the need for determination of ultratrace concentrations representative of real world samples, a sensitive and highly specific technique such as GC-ICP-MS is needed. A commercial GC speciation kit was recently developed for the Thermo Scientific ELEMENT 2/XR.
