The range of topics covered by the term specification varies from the determination of isotopic composition, through whether an element or nuclide is present and under which form, to the full identification of the molecular compound present or the isolation of species. Therefore, it is quite understandable that a rather large range of techniques may be applicable for specification purposes and that none may be sufficient by itself to cover all purposes.

The present report attempts to review technologies available for specification purposes in nuclear fuel cycle activities and to provide a reference document to guide researchers in choosing the most useful technique for their purposes by summarizing the characteristics. Particular attention has been given to highlight the advantages and disadvantages/limitations of a given technique as well as, when suitable, expected or necessary future improvements. It was also attempted to indicate a recommended application field, though this was not an easy task. The report concentrates on techniques available for macro concentration specification with an arbitrary limit fixed around 1E-6 M. However, one should be aware that some of the techniques discussed may also be applicable for lower concentration, and vice-versa. .
