UNSPSC 41113322: Nitrogen or nitrate or nitrite analyzer

UNSPSC 41113322 Nitrogen or nitrate or nitrite analyzer is a Commodity code, but the recent state and local opportunities posted under this code show little alignment with nitrogen, nitrate, or nitrite analysis. The nine opportunities identified span medical-grade oxygen supply (Collier County EMS), refrigerant gas extraction and recycling (City of Tucson), waste-to-energy facility demolition and operation (Solid Waste Authority of Palm Beach County), compressor gas coolers (City of Austin), hydrogen sulfide control chemicals (City of Orlando), atmospheric hazard-gas monitoring equipment (City of Phoenix), thermal and gas analysis laboratory instruments (University of Wisconsin-Madison), methane detection system maintenance (Orange County Transportation Authority), and Acrulog detectors (Gwinnett County, Georgia). Only the Phoenix atmospheric monitoring and OCTA methane detection opportunities involve detection or analysis of specific gases at fixed or operational points; the others address gas supply, extraction, chemical treatment, or thermal-gas laboratory analysis—functions distinct from the nitrogen/nitrate/nitrite analyzer scope the code nominally describes. The issuing bodies include municipalities, a county, a transit authority, a regional solid waste authority, and a university, drawn from Florida, Arizona, Texas, Georgia, and California.

The geographic spread spans Florida (Collier County, City of Orlando, Solid Waste Authority of Palm Beach County), Arizona (City of Tucson, City of Phoenix), Texas (City of Austin), Georgia (Gwinnett County), and California (Orange County Transportation Authority), with one Wisconsin higher-education buyer. Representative recent opportunities include the Orange County Transportation Authority's IFB 250322 for methane detection system service and maintenance across five transit facilities, with bids due June 1, 2026 and an estimated contract value of $260,000 over four years; the City of Phoenix IFB-27-0435 for atmospheric monitoring instruments-fixed at water and wastewater facilities, with offers due September 4, 2026 and a five-year term including 48-hour parts availability and technician certification requirements; and Collier County Emergency Medical Services' quotation for medical-grade oxygen supply with delivery, hydrostatic testing, and tank rental services (QQ2026152, due October 8, 2026, approximately $12,000 annually). The code appears to have been applied inconsistently across these opportunities; firms pursuing work in gas detection, atmospheric monitoring, or detection-system maintenance should verify actual commodity code alignment during pre-bid clarification.
