Reference Materials Catalogue : Price list (French version)
The quality standards that apply to laboratory analysis require that all analysis methods be validated before use. Reference materials are among the foremost tools used for validation. To meet requirements, these materials must have appropriate composition (natural and synthetic matrices), and be stable (known conservation time) and homogeneous (known consistent concentration).
Most laboratories have a unit that prepares control samples for in-house use. Yet, using control samples from outside sources contributes to increased control reliability. Reference materials manufactured by Centre d'expertise en analyse environnementale du Québec (CEAEQ) may be used as in-house control samples. This releases the laboratories from the need to create and maintain an in-house manufacturing unit. The CEAEQ delivers most reference materials throughout the world.
Several types of reference materials are offered in natural or artificial matrices: drinking water, groundwater, (municipal and industrial) wastewater, sewage treatment plant sludge, contaminated soil and hazardous materials (oil and industrial gaseous discharges). The CEAEQ may also prepare specific reference materials for several organic, inorganic and microbiologic parameters.
Reference materials are delivered with a certificate prepared in accordance with the ISO/CEI Guide 31. The materials are also used in proficiency testing that can be accessed by any laboratory that asks for them. Participants are provided with an evaluation report that includes all laboratory results.
The Centre d’expertise en analyse environnementale du Québec guarantees that all reference materials offered in its Catalogue meet the characteristics given.
