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.
Zircon 91500
This single crystal has been widely used for U-Th-Pb geochronology and δ18O studies and it has also been characterised for trace element and Hf-isotope contents. The relevant information is given in Wiedenbeck et al. (1995, 2004).

Reference Materials for Electron Microprobe
In the early 1990s a number of Harvard materials were characterized 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 characterized for their light element contents and isotopic compositions. These are described in Dyar et al. (2001) and Leeman et al. (2001).
