Certified Reference Materials
These
certified reference materials are used to monitor the accuracy of analyses
reported by mineral testing laboratories. They are a nominal 40 micron particle
size and are thoroughly blended to become as near to homogeneous as possible for
the particular sample matrix. They are used by laboratories to calibrate their
equipment and internal quality control, and used by mining companies to check
that the laboratories are reporting analyses to an acceptable degree of
accuracy.
We
have an extensive range of standard materials to choose from. These come from a
wide variety of sources and represent a good cross-section of sample matrices.
We have supplied these certified reference materials to a large number of
Australian projects and mines, as well as many consignments to Asia, Europe,
Africa, North America and South America.
The
tolerances attributed to these products have been assigned using values reported
in the six-monthly Geostats Laboratory Survey. Over one hundred laboratories
from all parts of the world take part in these surveys and the survey reports
are subscribed to by many of the senior mining houses both in Australia and in
other parts of the world.

Gold Certified Reference
Materials
We
have more than one hundred gold certified reference materials available,
ranging in values from 0.02 ppm Au to 47.24
ppm Au. We report both fire assay grades and aqua regia grades on all
these products.
Low Level Gold
Certified Reference Materials
Ten
low level gold certified reference materials
were introduced in 2001 and 10 new ones are added each year. These
materials all have a gold grade less than 100 ppb and are reported in
ppb.
Both of
these materials can be packaged in heat sealed plastic pulp packets (in
any weight) or 1kg tubs (as seen on left). |
 |
Carbon
Certified Reference Materials
Barren
and loaded carbon certified reference
materials are also available, with various gold
grades between 66 ppm and
7,769
ppm in stock. We report both gold and silver
values (if available) for these products.
These
materials are packaged in heat sealed foil pulp packets (in any weight)
as seen on left. |
 |
Base Metal Certified
Reference Materials
We
have more than one hundred base metal certified reference materials with
a wide range of values for copper, lead, zinc, nickel, arsenic, silver
and cobalt.
Ore
Grade Base Metal Certified Reference Materials
Ore
Grade Base Metals were introduced in October of 2003.
Currently we have six different certified reference materials
with values for copper, lead, zinc and nickel.
Both of
these materials can be packaged in heat sealed plastic pulp packets (in
any weight) or 250gm tubs (as seen on left).
|
 |
Sulphur Certified Reference
Materials
We
have more than 100 sulphur certified reference
materials manufactured solely for this element to enable higher grade
certified reference materials to be produced.
These
materials are packaged in heat sealed plastic pulp packets (in any
weight) as seen on left. |
 |
Multi-Element Certified
Reference Materials
We
have 6 multi-element certified reference materials that have statistics
for Gold by Fire Assay, Gold by Aqua Regia, Silver, Copper, Lead, Zinc,
Nickel, Arsenic, Cobalt and Sulphur.
These
materials can be packaged in either heat sealed foil packets or sealed
glass jars (as seen on left).
