Simultaneous chemical separation of Ge and Sb from Sb-rich sulfide samples for isotopic analysis using MC-ICP-MS

Key Points

• To develop a method for the simultaneous separation of germanium and antimony from sulfide samples for isotopic analysis.
• Utilized MC-ICP-MS for high-precision isotopic analysis.
• Developed a chemical separation protocol for germanium and antimony.
• Focused on Sb-rich sulfide samples, particularly those containing sphalerite.
• Successfully separated Ge and Sb, allowing for accurate isotopic measurements.
• Identified enrichment patterns of Ge and Sb in the samples analyzed.
