Direct Determination of Trace Impurities in High-Purity Molybdenum with the NexION 1100 ICP-MS

Introduction

High-purity molybdenum and its compounds are essential for producing scintillation materials used in ionizing radiation detectors for applications such as dark matter and double beta decay research. Ensuring material purity requires highly sensitive, multielement analytical methods. While ICP-MS is the preferred technique for trace impurity analysis, challenges such as spectral and doubly-charged interferences can affect accurate detection of certain elements.

Thanks to its true-quadrupole Universal Cell, the NexION^® 1100 ICP-MS, upgraded to two gas channels, can directly measure 21 elements in high-purity molybdenum, leveraging NH₃ Reaction and He Collision modes to eliminate matrix or polyatomic interferences, as needed, ensuring accurate results.
