UNSPSC 41113107: Nitrogen gas analyzers

UNSPSC 41113107 Nitrogen gas analyzers is a Commodity code that in practice spans a far broader range of gas-handling and atmospheric-monitoring equipment and services than the code name suggests. State and local governments are procuring atmospheric gas detection and monitoring systems, gas refill and specialty gas supply services, hydrogen sulfide control chemicals, and related installation and maintenance support. Recent opportunities show city and county environmental, water, wastewater, and transportation departments as primary buyers, along with state environmental agencies and university research facilities. The scope of work reflects operational and safety needs rather than analysis equipment alone — contractors are delivering fixed atmospheric monitoring sensor systems with installation and commissioning, multi-location chemical dosing services for corrosion and odor control, specialty gas refill operations with emergency availability, and preventive maintenance contracts with calibration and parts replacement at multiple customer sites.

Solicitations under this code cluster in the Southwest, Florida, and California. The City of Phoenix Water Services Department issued IFB-27-0435 for atmospheric monitoring instruments-fixed (sealed offers due September 4, 2026) to detect hydrogen sulfide, methane, oxygen depletion, and other hazardous gases across water and wastewater facilities with a five-year contract term and DBE-N compliance required. The City of Orlando solicited hydrogen sulfide control service (IFB 260556, proposals due September 9, 2026) for chemical application at three lift stations. The Orange County Transportation Authority issued IFB 250322 for methane detection system service and maintenance across five facilities (bids due June 1, 2026) under prevailing wage and DBE requirements with an estimated four-year value of $260,000. Collier County Emergency Medical Services (Solicitation QQ2026152, quote due October 8, 2026) is procuring medical-grade oxygen supply in multiple tank sizes with tank rental, hydrostatic testing, and emergency delivery capability. The California Department of Toxic Substances Control issued IFB I-2627-03 for specialty gas refill services (liquid argon and nitrogen, bids due August 31, 2026). The City of Austin sought Compressor Gas Cooler ECM-2 units under two separate IFQs in July and September 2026. Activity spans Florida, California, Arizona, and Texas, with secondary opportunities in Georgia and other states.
