UNSPSC 41113100: Gas analyzers and monitors

UNSPSC 41113100 Gas analyzers and monitors, a Class code, encompasses portable and fixed gas detection equipment, continuous emissions monitoring systems, calibration devices, and associated maintenance and refill services that state and local governments deploy across water utilities, wastewater treatment, environmental agencies, emergency medical services, and waste-to-energy facilities. Recent solicitations show procurement of medical-grade oxygen supply and tank management, EPA-certified refrigerant recovery and documentation services, methane and hydrogen sulfide detection systems with ongoing calibration and maintenance, portable emissions measurement equipment for air quality compliance, and specialty gas refill services for laboratory operations. Issuing bodies span municipal water and sewer commissions, county environmental and waste management departments, state environmental protection agencies, fire and emergency services, transportation authorities, and university research programs. The code draws activity from both routine operational support (oxygen supply to ambulances, gas detection at treatment facilities) and compliance-driven procurement (emissions monitoring for air quality surveillance, refrigerant recovery for environmental regulations).

Geographic activity clusters in Florida (Collier County EMS, City of Orlando, Solid Waste Authority of Palm Beach County, Florida Department of Environmental Protection), California (City of Tucson, Orange County Transportation Authority, California Department of Toxic Substances Control, California Air Resources Board), and scattered across Arizona, Massachusetts, Georgia, Illinois, and Idaho. Recent representative opportunities include Collier County Emergency Medical Services' solicitation for medical-grade oxygen supply with tank rental and hydrostatic testing through October 1, 2026 under an IFB with approximately $12,000 annual spend; the City of Phoenix Water Services Department's IFB-27-0435 for atmospheric monitoring instruments with hydrogen sulfide and methane detection across five facilities, due September 4, 2026, under a five-year term with DBE-N participation requirements; the Orange County Transportation Authority's IFB 250322 for methane detection system service and maintenance across five transit bases at $260,000 over four years, due June 1, 2026, subject to prevailing wage and Davis-Bacon requirements; and the California Air Resources Board's RFQ for portable emissions measurement systems and AVL quality control equipment, due May 21, 2026, with small business and DVBE preferences available.
