Reference Materials

**Although we are currently taking requests, we are unable to ship the reference materials at this time and do not expect shipments to resume for several months.**

Mineral Sciences provides reference materials to help scientists calibrate instruments and monitor the quality of analyses. Smithsonian reference materials are used in laboratories worldwide and fill a vital need in the scientific community.

The following reference materials are currently available:

• Allende Reference Powder
• SIMS reference materials for measuring water in mantle minerals (Kumamoto et al., 2017)
• Smithsonian Microbeam Standards
