Use of a direct current glow discharge mass spectrometer for the chemical characterization of samples of nuclear concern
Direct current glow discharge mass spectrometry (GDMS) has been applied to different types of nuclear fuels, cladding materials and nuclear-waste glasses. For the non-conducting oxide-based nuclear samples the relative sensitivity factors (RSF), applied for quantitative analysis, are affected by the oxygen content in the matrix. The effect of 'getter metals,' such as tantalum and titanium as binder material, has been investigated. When tantalum was used as a secondary cathode, it was found to behave as a getter of oxygen. For the quantitative analysis of nuclear-waste glasses the use of matrix specific RSFs was necessary. Comparisons with RSFs obtained from other work are made. Metallic alloys were analysed using several analytical techniques. The GDMS results were in agreement with those from independent techniques.
