NIGP 49314: Combustion Analysis Equipment, Automatic (for Carbon, Nitrogen, Sulfur, etc.)

NIGP Item 49314 Combustion Analysis Equipment, Automatic (for Carbon, Nitrogen, Sulfur, Etc.) covers analytical instruments that municipalities and water agencies deploy to measure elemental composition in environmental compliance work — specifically, nitrogen balance modeling in wastewater treatment and atmospheric hazard detection in water and wastewater operations. State and local governments under this code are buying fixed atmospheric monitoring systems with sensors, controllers, alarms, and calibration materials designed to detect hydrogen sulfide, methane, oxygen depletion, chlorine, ammonia, ozone, chlorine dioxide, and carbon monoxide at lift stations, headworks facilities, chemical storage rooms, and confined spaces. The issuing bodies soliciting under the code include municipal water service departments and cities operating land application wastewater sites; the scope reflects environmental compliance obligations under state and federal wastewater permits and water quality regulations rather than pure laboratory or academic research.

Recent activity centers in Texas and Arizona. The City of Lubbock posted a Statement of Qualifications (RFQ2619882SR, due September 30, 2026) for wastewater land application consulting that requires day-to-day operation and maintenance of water and nitrogen balance models at two facilities to prevent nitrate leaching into groundwater under Texas Commission on Environmental Quality permits. The City of Phoenix Water Services Department issued an Invitation for Bid (IFB270435, due September 4, 2026) for fixed atmospheric monitoring instruments with a five-year firm contract term, DBE-N program participation requirements, and mandatory 48-hour replacement parts availability. Both solicitations demand certified technician support, operator training, and equipment manufacturers including ATI, De Nora, Drager, or MSA. Contract values and full performance locations beyond the named sites are not specified in the available records.
