UNSPSC 41115719: Gas chromatography liners

UNSPSC 41115719 Gas chromatography liners is a Commodity code. Recent state and local solicitations tagged with this code show little direct alignment with the code's nominal scope—opportunities instead involve purchase of analytical instrumentation systems (liquid chromatograph-triple quadrupole mass spectrometry equipment), broad laboratory testing services contracts (water, wastewater, and groundwater analysis), and laboratory consumables for specific analyte detection (PFAS and dioxane cartridges and vials). The mismatch suggests that state and local procurement offices are using this code to tag analytical laboratory work more broadly, rather than specifically for gas chromatography liner consumables. Where the code does apply to genuine liner or consumable procurement, state and local governments appear to be sourcing these items as part of larger instrument acquisitions, testing service contracts, or bundled lab-supply agreements rather than as standalone commodity purchases.

The issuing bodies include county governments (Brazoria County, Texas Sheriff's Office) and municipalities (City of Palm Bay, Florida; City of Tucson, Arizona), with activity concentrated in Texas, Florida, and Arizona. Representative opportunities include Brazoria County's RFP for an LC-QQQ mass spectrometry system with installation, training, and integration, due May 12, 2026, estimated budget $300,000; the City of Palm Bay's ITB 19-ITB-26 for comprehensive laboratory testing services across water and wastewater facilities, with bids received in March 2026 ranging from $80,872 to $107,946 annually; and the City of Tucson's IFB 240045 for Waters Technologies brand consumables (cartridges and vials) for PFAS and dioxane analysis. Set-asides and compliance requirements vary—the Tucson procurement includes HUD Section 3 workforce development requirements, while the Brazoria County system procurement is funded through the Paul Coverdell Forensic Sciences Improvement Grant and subject to prevailing wage standards.
