Determination of trace elements in radioactive and toxic materials by ICP-MS

The need of fast, quantitative and elemental mapping analysis of impurities in radioactive and toxic materials led to the development of a glove box ICP-MS in this laboratory. On that occasion, a very simple determination method has been investigated. Based on the use of internal standards and appropriate dilutions, it requires neither previous separation of the matrix nor its reconstitution for the calibration. Since the nuclearization of the spectrometer in 1993, hundreds of uranium and plutonium samples have been analyzed and the concentration of 55 elements routinely determined. This method was also applied to other matrixes, especially beryllium. This work describes the optimized parameters of the method as well as its efficiency. For this purpose, the concentrations of a number of impurities have been compared with those obtained with spark source mass spectrometry (SSMS) and atomic emission spectrometry (ICP-AES). The agreement between the different sets of results is quite good. Moreover, detection limits are often lower with ICP-MS than with SSMS, although the sensitivity of the method suffers from the necessary dilution of the sample.
