Calibrating Gas Mixture Formulation and Certification

A subcontract is solicited to develop, blend, and certify a non-flammable calibrating gas mixture composed of nitrogen with exactly 10 parts per million of hydrogen cyanide, tailored to meet stringent OSHA and military standards for precise concentration accuracy and long-term stability. The mixture must be manufactured under controlled conditions to ensure consistency, safety, and compliance with regulatory requirements for use in calibration applications within sensitive environments. The work requires specialized expertise in gas formulation, certification protocols, and adherence to hazardous material handling procedures. The opportunity is posted under NAICS code 325120, indicating chemical manufacturing, and is managed by the Department of Defense’s Aviation Supply Chain ESOC Buys organization. Performance is required to take place in Williamsburg, Virginia, with a zip code of 23185-5830. Interested parties must submit responses by May 7, 2026, following the solicitation issued on April 29, 2026. This is a subcontract engagement, suggesting the selected vendor will support a larger procurement effort, likely supplying certified gas standards to defense or aviation systems requiring reliable and validated calibration sources.
