Over 99% of the reference standards in the Restek catalog are certified reference materials (CRMs), and that includes both single-component and multicomponent mixes. Restek has also maintained ISO 9001 registration since 1994. Put another way, almost all of our stock reference standards are officially recognized as being manufactured and QC tested under the world-class quality standards established by the International Organization for Standardization (ISO). Many laboratories are required to purchase CRMs to satisfy their own ISO requirements, but even if you are not, you can still benefit from the performance, reliability, and consistency of Restek reference standards.
