UNSPSC 41115730: High pressure liquid chromatography HPLC guard column

Replaceable media placed before an HPLC column which provides contamination protection.

UNSPSC 41115730 High pressure liquid chromatography HPLC guard column is a Commodity code covering consumable laboratory supplies and specialized analytical chemistry components procured by state and local public safety, forensic, and environmental agencies. Recent state and local solicitations show that buyers are acquiring HPLC-related reagents, cartridges, buffers, and consumable lab supplies for use in genetic analysis, forensic toxicology screening, and drug detection alongside broader procurements of liquid chromatography instrumentation. The issuing bodies include state-level centralized procurement divisions (the Texas Comptroller of Public Accounts) acting on behalf of state law enforcement and environmental agencies (Texas Department of Public Safety, Texas Department of Parks and Wildlife), as well as county sheriffs' offices and crime labs seeking both consumables and instruments.

Texas dominates recent activity under this code. The Texas Comptroller of Public Accounts issued an IFB (Solicitation 304T27175A11) on September 23, 2026, with a response deadline of October 20, 2026 at 1:00 p.m. CST, for proprietary chemical laboratory equipment and supplies including DNA analysis reagents, sequencing kits, and drug screening consumables sourced from Life Technologies, Promega, Qiagen, Immunalysis, and ANDE, with expected quantities per line item ranging from 8 to 5,000 units over a four-year term. Brazoria County, Texas also issued an RFP (2648) posted May 12, 2026, for acquisition of a Liquid Chromatograph-Triple Quadrupole Mass Spectrometer system for its Sheriff's Office Crime Lab, demonstrating concurrent demand for both consumables and capital instrumentation in forensic chemistry workflows.
