• In-situ Rb-Sr dating of micas (no mineral separation needed)
• Mineral trace element analysis (including Cl, Br, and low level sulfur (~10 ppm S))
• Mineral trace element mapping. Examples:

Capacities in Development

• U-Pb dating of titanite, monzonite, apatite, and wolframite
• In-situ S isotope composition analysis
