UNSPSC 41115727: Chromatography blotting paper

A blotting paper composed of superclean cotton or cellulose that is utilized during the stationary phase of thin layer chromatography to ensure wicking capability and uniformity of capillary action

UNSPSC 41115727 Chromatography blotting paper is a Commodity code, but the recent state and local opportunities tagged under it do not align with chromatography consumables—they cover liquid chromatography-mass spectrometry (LC-MS) instrumentation, laboratory testing services, and laboratory consumables for PFAS analysis. The actual work being solicited under this code designation includes acquisition of complete LC-QQQ analytical systems with delivery, installation, training, and integration; comprehensive water and wastewater testing services across municipal treatment facilities; and purchase of laboratory consumables such as cartridges and vials for drinking water analysis. Issuing bodies include county sheriff's offices, municipal water and wastewater utilities, and city water departments. The solicitations span county-level procurement (Brazoria County, Texas) and municipal purchasing (City of Palm Bay, Florida; City of Tucson, Arizona).

Geographic activity appears concentrated in Texas, Florida, and Arizona based on recent postings. The City of Palm Bay, Florida issued ITB 19-ITB-26 for laboratory testing services due March 17, 2026, requiring certified laboratories with five years' experience serving municipal water and wastewater utilities; three bids were received, ranging from $80,872 to $107,946 in total annual pricing. Brazoria County, Texas issued RFP 26-48 for a complete LC-QQQ system with a $300 million estimated budget, funded through the Paul Coverdell Forensic Sciences Improvement Grant Program, with proposals due May 12, 2026; the procurement specifies 25 points for technical compliance, 20 for price, 15 for experience, 20 for training, and 10 each for warranty and delivery timeline. The City of Tucson, Arizona issued IFB 240045 for Waters Technologies brand consumables for PFAS and Dioxane analysis with a HUD Section 3 set-aside requirement (25 percent of labor hours performed by Section 3 workers, 5 percent by Targeted Section 3 workers); the contract structure allowed multiple awards to ensure consumables availability.
