UNSPSC 41113111: Ozone analyzers

UNSPSC 41113111 Ozone analyzers (Commodity) encompasses portable and bench-top instruments for real-time measurement of ozone concentration in ambient air, along with calibration systems, replacement parts, and associated technical support—equipment state and local environmental agencies deploy across monitoring networks to track air quality compliance with EPA standards. The code sees solicitation activity from state environmental agencies, regional water authorities, and city governments, with Texas leading recent procurements through the Texas Commission on Environmental Quality (TCEQ), which has posted multiple competitive bids for ozone analyzers, ozone precursor monitoring systems, calibrators, and replacement parts over the past four months.

The geographic concentration is pronounced: TCEQ alone has issued at least seven solicitations under or closely aligned with this code since late February 2026—RFB 582-26-15242 (UV Photometric Ozone Calibrator and dynamic dilution calibrator, due February 25, 2026), RFB 582-26-15508 (dynamic dilution calibrator and zero air supply system, due April 20, 2026), RFB 582-26-15573 (hydrogen sulfide cavity ringdown spectrometer, due June 10, 2026), RFB 582-26-15833 (Ozone Precursor Monitoring System with thermal desorption gas chromatograph, due April 15, 2026), and RFB 582-26-15418 (BAM 1022 air monitoring system replacement parts including filter tape and pump assemblies, due June 11, 2026)—all as IFB notices with firm pricing for 30 days from opening and delivery FOB destination to Austin facilities. Outside Texas, the Colorado Department of Public Health and Environment issued RFP 2026000164 (air monitoring instrumentation vendor pool including ozone analyzers and calibrators, due April 7, 2026) with a five-year budget ceiling of $8 million; the Commonwealth of Kentucky procured one dual-channel canister and carbonyl sampler (RFB due March 18, 2026); the Michigan Department of Environment, Great Lakes, and Energy solicited an air monitoring shelter (RFP due July 1, 2026); and Tampa Bay Water announced sole-source procurement of ozone gas analytical equipment and services from Ozone Systems and Technology International (notice deadline February 25, 2026). The City of Philadelphia posted two sound calibrator micro-purchase RFQs (due June 5 and July 23, 2026), though these diverge from ozone analysis into acoustic measurement. Activity clusters in Texas, Colorado, and the Great Lakes/Southeast regions, with TCEQ representing the dominant repeat buyer and most aggressive procurement pace.
