UNSPSC 41113108: Nitrogen oxide analyzers

UNSPSC 41113108 Nitrogen oxide analyzers is a Commodity code that encompasses analytical instruments and systems for detecting and measuring nitrogen oxides and related gases, but the recent state and local activity under this code shows limited direct alignment with the nominal scope. The source records nine recent state and local solicitations tagged to the code, yet only two — a University of Wisconsin-Madison bid for a Simultaneous Thermal and Gas Analysis System (RFB 2027UWMSN01387, due July 17, 2026) and Orange County Transportation Authority's IFB 250322 for methane detection system service and maintenance across five facilities ($260,000 over four years, due June 1, 2026) — involve gas monitoring or detection equipment that falls squarely within the code's analytical instrumentation scope. The remaining seven opportunities address medical-grade oxygen supply (Detroit Fire Department RFQ 545340), school district instructional resources (Klein ISD RFP 26-101), lab information management systems (Santa Clara County RFI), particulate matter monitoring equipment (Fort Worth RFQt 26-0142), landfill gas consulting services (Greenville County RFP 26092), ChemScan analyzer support (City of Tampa ISS 26X01038), and a digester gas utilization project (Eastern Municipal Water District RFP 3900) — procurement activities that span water quality, environmental remediation, waste management, and energy production rather than nitrogen oxide analysis specifically.

The issuing bodies represented are diverse: higher education (University of Wisconsin-Madison), county transit and water authorities (Orange County Transportation Authority, Eastern Municipal Water District, Santa Clara County), municipal governments (City of Tampa, City of Detroit, City of Fort Worth, Greenville County), and independent school districts (Klein ISD). Geographic activity spans Wisconsin, California (Orange County, Santa Clara County, Riverside County), Texas (Harris County, Tarrant County), Florida (Hillsborough County), Michigan, and South Carolina. The code shows scattered recent activity with no dominant repeat buyer or concentrated geographic cluster; the two opportunities most closely aligned with nitrogen oxide or gas analysis instruments — the Wisconsin thermal and gas analysis system and the Orange County methane detection service contract — suggest that when the code does generate relevant procurement, work involves equipment calibration, maintenance, monitoring networks at municipal utilities and research institutions, and compliance with air quality or waste-gas regulatory regimes. The mismatch between the code's nominal scope and most of the tagged opportunities suggests either tagging inconsistency in the issuing systems or that this Commodity code captures only a fraction of state and local demand for gas analysis instrumentation, with many similar procurements classified elsewhere.
