UNSPSC 41115708: High pressure thin layer chromatograph TLC

UNSPSC 41115708 High pressure thin layer chromatograph TLC is a Commodity code that in recent state and local practice encompasses analytical laboratory instrumentation and consumables used for forensic, environmental, and public health testing — a scope notably broader than the code's nominal name. Recent solicitations show state and local governments buying liquid chromatograph-mass spectrometer systems for forensic laboratories, laboratory testing services for water and wastewater regulatory compliance, and specialized consumables for drinking water analysis. The issuing bodies include county sheriff's offices (forensic laboratories), municipal water utilities, and city environmental departments. Brazoria County, Texas appears as a repeat buyer, with two separate RFP notices posted in April and May 2026 for the same LC-QQQ system acquisition.
