Certified Reference Materials

Certificates of Analysis for Older Reference Materials

Certificates of Older Reference Materials can be made available upon request.

Please note that "30g" and "50g" are nominal values only. Approximately 2 grams extra are included in each sachet so that it is easier to scoop out the nominal weight without having to scrape out the last traces of powder in the bottom of the sachet.

The sachets are available with either Labcheck or Geocheck labels. Labcheck labels have the name of the Reference Material (e.g. WG2) clearly stated on the label. Geocheck labels do not have the name of the Reference Material stated on the label but do have a unique number for ready identification by the purchaser. Jars are packed in cartons containing 6 jars (i.e. 15 kg) but the minimum order is one jar.

Customised Reference Materials

For mine material or exploration targets that have an unusual matrix, we may be able to produce a custom reference material for you. We use only known, stable materials and screened minerals with finely divided gold to match your matrix. The matrix-matched mineral components will be blended and packaged to your preference in sachets or jars, and a formal homogeneity test carried out. Samples can be sent out for consensus testing and a formal certificate can be supplied if required.
