UNSPSC 41113113: Sulfur dioxide analyzers or detectors

UNSPSC 41113113 Sulfur dioxide analyzers or detectors (Commodity) shows little activity directly aligned with the code's nominal scope. The recent opportunities tagged to this code span environmental monitoring equipment, lab information systems, wastewater treatment components, medical oxygen supply, and educational materials—none of which are sulfur dioxide analyzers or detectors. The Orange County Transportation Authority (OCTA) IFB 250322 for methane detection system service and maintenance is the closest match, involving SEC-3100 sensor transmitters and Sierra Monitor gas monitoring systems across five transit facilities under a $260,000 four-year prevailing-wage contract with Davis-Bacon requirements and DBE compliance; however, the scope is methane detection, not sulfur dioxide. The City of Fort Worth's RFQt #26-0142 (due March 23, 2026) for portable real-time particulate matter monitoring equipment and the University of Wisconsin-Madison's thermal and gas analysis system bid (due July 17, 2026) represent air and gas quality monitoring but do not target sulfur dioxide specifically. The remaining opportunities—Tampa's ChemScan analyzer parts and service, Detroit's medical oxygen supply, Santa Clara County's lab information system RFI, Klein ISD's career technical education materials, and Greenville County's landfill gas consulting—are unrelated to the code's scope.

Issuing bodies in the recent record include a university procurement office, a regional transit authority, cities, counties, and a school district, suggesting the code may be tagged to environmental monitoring and analytical equipment procurements more broadly. Geographic activity appears in California (OCTA, Eastern Municipal Water District), Texas (Fort Worth, Klein ISD), Florida (Tampa), Michigan (Detroit), South Carolina (Greenville County), Wisconsin (University of Wisconsin-Madison), and California again (Santa Clara County). The mismatch between the code definition and actual solicitations indicates either tagging error or that state and local procurement offices apply this code inconsistently across gas detection and analytical equipment categories. Firms pursuing gas-detection or environmental monitoring work should verify specific equipment requirements in RFPs before assuming relevance under this UNSPSC number.
