Development of an optimised method for analysis of90Sr in decommissioning wastes by triple quadrupole inductively coupled plasma mass spectrometry.
The ongoing development of an optimised procedure for the measurement of90Sr in decommissioning samples using the latest generation triple quadrupole inductively coupled plasma mass spectrometry (ICP-QQQ-MS) is presented. The procedure incorporates digestion, and separation from interferences using a combination of wet chemical and instrument-based separation using the ICP-QQQ-MS reaction cell. The key factors under study are the procedural time and limits of detection achievable compared to existing radiometric techniques.
