High precision selenium isotope analysis using a Nu Sapphire collision–reaction cell MC-ICP-MS
Journal Article Journal of Analytical Atomic Spectrometry · October 1, 2025 Selenium is a redox-sensitive trace element that is both an essential nutrient and toxin. Studying selenium cycling in nature is of great interest to the fields of environmental health, geomicrobiology, chemical oceanography and volcanology. The six stable ...
