UNSPSC 41113106: Infra red or ultra violet absorption analyzers

UNSPSC 41113106 Infrared or Ultraviolet Absorption Analyzers is a Commodity code under which state and local governments procure analytical equipment for environmental monitoring, wastewater treatment, and laboratory applications. Recent solicitations show procurement of specialized analyzer systems for thermal analysis, methane detection, and air-quality particulate monitoring rather than commodity-level absorption spectrometers alone. Issuing bodies span universities, transit authorities, municipal utilities, county environmental agencies, and municipal water districts. The University of Wisconsin-Madison sought a Simultaneous Thermal and Gas Analysis System (IFB, due July 17, 2026); the Orange County Transportation Authority solicited service and maintenance for methane detection systems including SEC-3100 sensors, General Monitor IR5000 open-path hydrocarbon gas monitors, and Sierra Monitor detection units across five facilities ($260,000 estimated value, four-year term, IFB 250322, response deadline June 1, 2026); the City of Fort Worth requested portable real-time particulate matter monitoring equipment for field-based environmental inspections (RFQt 26-0142, due March 23, 2026); and the City of Tampa issued an intent to single source replacement parts and authorized service for a ChemScan Process Analyzer System used by the Wastewater Department (ISS, due April 9, 2026).

Geographic activity clusters in California and Texas, with additional solicitations in Wisconsin, Florida, Michigan, and South Carolina. The Eastern Municipal Water District in Riverside County posted a large design-build-finance-own-operate project for digester gas utilization at three Regional Water Reclamation Facilities (RFP 3900, due April 14, 2026), requiring digester gas analysis and monitoring as part of renewable energy conversion infrastructure. Greenville County, South Carolina issued RFP 26092 for landfill gas and air-quality consulting services covering three county landfills, with emphasis on Title V compliance reporting and gas data evaluation (due April 1, 2026). The County of Santa Clara posted an RFI for a Public Health Lab Information Management System replacement (due April 22, 2026), which does not directly align with analyzer hardware procurement. Activity skews toward environmental and wastewater applications where infrared and ultraviolet detection supports regulatory compliance, gas monitoring, and process control rather than standalone laboratory analysis.
