Sonic Nozzle Gas Mixing Systems

The National Institute of Standards and Technology (NIST) is seeking three (3) sonic nozzle gas mixing systems as part of its CHIPS Metrology Program under Grand Challenge 1: Metrology for Materials Purity, Properties and Provenance. These analytical instruments will be used to certify semiconductor and electronics gases at part-per-trillion levels and safely dilute toxic gases for optical instrument analysis, supporting NIST's Chemical Science Division's efforts to detect trace impurities in gas-phase samples relevant to the semiconductor industry. The systems must meet precise technical specifications including sonic nozzles/orifices, multiple gas inlets and outlets, 1/4-inch metal gasket face seal fittings, and 1024 source gas dilution points. This pre-solicitation notice, posted on November 17, 2025, serves as a sources sought announcement to identify potential vendors capable of manufacturing instruments meeting these exacting technical requirements. Interested contractors should note the December 1, 2025 due date for responses to this sources sought notice, which will inform the development of the formal solicitation to follow.

No set-aside designations have been applied to this procurement opportunity. The notice does not identify any current incumbents, potential awardees, or specific budget allocations. The procurement focuses on the acquisition of specialized analytical laboratory instruments rather than services, with the quantity fixed at three complete gas mixing systems for NIST's semiconductor metrology research and certification operations. No timeline for service delivery, performance period, or award value information is provided in this pre-solicitation stage. Vendors responding to this sources sought notice should be prepared to demonstrate manufacturing capabilities in analytical laboratory instrument production and experience with complex gas handling and mixing systems designed for precision semiconductor gas certification applications.
