Frequently Asked Questions

What is the difference between NIST traceable and accredited?

NIST traceable means the gas standard's concentration values are linked through documented measurements to recognized NIST references. Accredited usually refers to a laboratory or quality system that has been independently assessed against a formal standard, such as ISO requirements. A gas mixture can be NIST traceable without the producer itself holding a separate accreditation, so buyers should review both traceability documentation and the supplier's quality controls.
