UNSPSC 41115729: Ion chromatography IC guard column

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

UNSPSC 41115729 Ion chromatography IC guard column is a Commodity code that describes consumable chromatography columns and related laboratory column components used in analytical chemistry workflows, though recent state and local activity under this code focuses more broadly on specialized forensic and clinical laboratory consumables, reagents, and instrumentation rather than chromatography columns specifically. State and local governments procure these items for crime laboratories, public safety forensic units, and state health or environmental testing facilities. The issuing bodies include state procurement offices managing statewide contracts, county sheriffs' offices operating crime labs, and special-purpose public safety agencies. Solicitations reflect a mix of consumable supply contracts serving multiple agencies at once and equipment acquisitions for individual laboratory facilities.

Texas dominates recent activity under this code, with the Texas Comptroller of Public Accounts issuing an IFB (304T27175A11) on September 23, 2026, due October 20, 2026, for proprietary chemical laboratory equipment and supplies serving the Texas Department of Public Safety and Texas Department of Parks and Wildlife statewide, covering DNA analysis kits, forensic reagents, drug-screening consumables, and specialized cartridges across 50 line items with designated vendors (Life Technologies Corp., Promega, Qiagen, Immunalysis Corporation, and ANDE Corporation). Brazoria County, Texas posted an RFP (#26-48) on May 12, 2026, for acquisition of a Liquid Chromatograph-Triple Quadrupole Mass Spectrometer system for its Sheriff's Office Crime Lab, with sealed electronic bids due the same day through the Bonfire platform. Both opportunities reflect procurement patterns favoring brand-specific or proprietary specifications tied to existing laboratory infrastructure and DNA analyzer compatibility.
