On account of its high sensitivity and multi-isotopic capabilities the technique of ICP-MS has been employed for the characterisation of spent nuclear fuels. Samples of relatively low activity, such as diluted solutions arising from the dissolution of spent fuels, can be handled in a glove-box and both elemental and isotopic information can be quickly gathered for most of the fission products and actinides. However, the methodologies applied for the analysis of nuclear samples by ICP-MS differ from those employed for natural elements. In this paper the on-line coupling of a chromatographic system with an ICP-MS installed in a glove box is described. Examples of the analysis of heavy fission products (Cs, Ba, lanthanides) separated on-line by ion chromatography are presented.
