UNSPSC 40161706: Nitrogen generator

Nitrogen generator is a unit for separating nitrogen gas from pressurized air, using either a membrane or PSA (pressure swing adsorption) principle.

UNSPSC 40161706 Nitrogen generator is a Commodity code that does not reflect the work state and local governments are actually procuring under this taxonomy entry. Recent state and local solicitations tagged with this code span specialized laboratory and research equipment across disciplines—X-ray diffractometers, gas cluster ion beam systems, induction melting furnaces, microfluidizers, surface characterization platforms, and dynamic mechanical analyzers—none of which are nitrogen generators or generator-class equipment. The mismatch between the code label and the recent opportunities suggests either systematic mis-tagging by issuing bodies or that this code has drifted in practice to capture a broader category of precision research instrumentation and consumables than the code name implies. The opportunities show university purchasing departments (Mississippi State University, University of Mississippi, University of Wisconsin-Madison, Texas State University, Midwestern State University) as the primary issuing bodies, along with occasional state agencies and county procurement offices. Sole-source designations dominate the recent activity, reflecting the specialized and often proprietary nature of the equipment being acquired.

Mississippi State University accounts for the largest share of recent opportunities, filing approximately 20 sole-source notices between June and October 2026 for equipment ranging from $6,000 to $1.25 million, with objection deadlines typically 10–14 days after posting. Representative recent solicitations include a Redwire Stalker Block 40 UAV for $2.086 million (posted October 9, 2026; objections due October 23) supporting a Department of Homeland Security project, a CEAD B.V. AM Flexbot 3D printing system for $1.253 million (posted September 11; objections due September 25), and a VRC Metal Systems Gen IV cold spray additive manufacturing system for $951,755.46 (posted August 18; objections due September 1). Geographic concentration is heavy in Mississippi, with secondary activity in Wisconsin, Texas, Illinois, and Oregon. The code shows no recent competitive RFP, RFQ, IFB, or ITB opportunities; all posted activities are sole-source notices or sealed-bid requests with minimal scope disclosure in the summary notices. This pattern signals a low-activity or mis-classified code that does not reflect current state and local procurement strategy for any coherent commodity family.
