UNSPSC 41151610: Thin-layer chromatography system for clinical use

In this classification a thin-layer chromatography (TLC) system for clinical use is a device intended to separate one or more drugs or compounds from a mixture. The mixture of compounds is absorbed onto a stationary phase or thin layer of inert material (e.g., cellulose, alumina, etc.) and eluted off by a moving solvent (moving phase) until equilibrium occurs between the two phases US FDA regulates Thin-layer chromatography system for clinical use under 21 CFR 862.2270 and under FDA product code KZS.

UNSPSC 41151610 Thin-layer chromatography system for clinical use is a Commodity code that sees minimal recent state and local procurement activity aligned with its nominal scope. The recent opportunities posted under this code span analytical laboratory instrumentation, water quality testing reagents, and related laboratory supplies — but none directly match thin-layer chromatography systems for clinical use. Instead, the opportunities cluster around liquid chromatography–mass spectrometry systems, ion chromatography equipment, gas chromatography systems, laboratory information management solutions, and specialized analytical instruments (spectrometers, infiltrometers, respirator fit testers, sound level meters, and pump calibrators) across crime labs, public health labs, environmental testing facilities, and academic research centers.

The issuing bodies are predominantly higher-education institutions (Mississippi State University, University of Southern Mississippi, University of Wisconsin–Madison, Texas A&M University System, University of Mississippi) and county and municipal laboratories (Broward County Florida, Santa Clara County California, Brazoria County Texas, Gwinnett County Georgia, Albuquerque, Philadelphia). Geographic activity concentrates in Mississippi, with secondary presence in Texas, Florida, Oregon, and the West Coast. Representative recent opportunities include the Texas Health and Human Services Commission procurement of COLILERT reagents and water bottles for bacteriological testing (due July 8, 2026, RFQ format, estimated historical annual spend $70,050–$90,000), Broward County's Request for Information on gas chromatograph–flame ionization detector system maintenance (due May 13, 2026), and the County of Santa Clara's lab information management system replacement RFI (due April 22, 2026). The code shows no active pursuit of thin-layer chromatography systems in particular and little decision-relevant procurement activity for that specific commodity line in the recent state and local market.
