Introduction
High-purity molybdenum (Mo) and its compounds are important in producing scintillation materials, whose performance is highly sensitive to trace metal content. As purity standards rise, inductively coupled plasma mass spectrometry (ICP-MS) is the preferred method for detecting low-level contaminants. However, ICP-MS faces challenges from polyatomic spectral interferences during analysis.
This work demonstrates the ability of the NexION® 5000 multi-quadrupole ICP-MS to directly measure 21 elements in high-purity molybdenum, using pure ammonia and oxygen reaction gases to facilitate the removal of interferences and aid the detection of elements with trace concentration.
