Physical Methods in Chemistry and Nano Science. Volume 4: Chemical SpeciationThis Series intended as a survey of research techniques used in modern chemistry, materials science, and nanoscience. The topics are grouped into volumes, not be method per se, but with regard to the type of information that can be obtained. Thus, the Volumes are ordered as follows: 1) Elemental composition; 2) Physical and thermal analysis; 3) Chromatography; 4) Chemical speciation; 5) Molecular and solid state structure; 6) Surface morphology and
