A number of microanalytical reference materials are available for purchase from IAGeo Limited, most of which are from our collaboration with the Mineralogical and Geological Museum, Harvard University. A single aliquot consists of approximately 100 mg of material.
Details of Zircon 91500 (U-Th-Pb geochronology) and the set of 3 tourmalines (dravite, schorl, elbaite) characterised for Li, B and O isotopes can be found under Isotope Ratio RMs.
Reference Materials for Electron Microprobe
In the early 1990s a number of Harvard materials were characterised for use as RMs specifically for the analysis of oxygen concentration as determined by electron microprobe. These are described in McGuire et al. (1992).

Reference Materials for Light Elements
In the early 2000s a suite of mineral phases was characterised for their light element contents and isotopic compositions. These are described in Dyar et al. (2001) and Leeman et al. (2001).
