Importance of measurements
Thousands of chemical and biological measurements are carried out around the world every day. They are used in all areas of technical and scientific activity. In industry, these measurements are used as quality control tools for raw and manufactured materials. Product verification may be solely for the purpose of quality control (e.g. conformity of production to meet quality standards required by customers) and/or regulatory compliance (e.g. product safety, compliance with a standard, etc.); it may also play a key role in monitoring production processes, controlling the potential impact of production on the environment, or assessing health and safety in the workplace.

Trade magazines
Strictly speaking, there are no specialized journals dealing solely with reference materials. Information is regularly published in the main scientific journals dealing with fundamental or applied analytical chemistry. A reference work written by the authors of this article (dealing essentially with interlaboratory tests and reference materials for environmental analysis) was published by Elsevier in 1999
Producers of reference materials
There are over 150 producers of reference materials worldwide. Information on their products can be obtained via the COMAR database available from the Laboratoire National d'Essais. It should be noted that in the absence of mandatory production quality criteria, in particular accreditation, it is difficult to assess the quality of all materials available on the market. Among the major producers are two...

Economic data
Material prices obviously vary according to the nature and complexity of the certified matrices. A few grams of pure materials (e.g. alloys) cost between 60 and 200 euros; the price of ampoules of materials for clinical analysis (e.g. serum, blood) can be in the same range, while matrix materials (e.g. residual sludge, sediments, etc.) can cost up to 300 euros per unit. These cost differences are obviously linked to production...
