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 that captures state and local government purchases of analytical laboratory consumables and components supporting environmental and forensic testing programs. Recent solicitations show that state and local agencies use this code to procure not only HPLC consumables such as guard columns and cartridges, but also complete analytical instrumentation systems (liquid chromatograph-triple quadrupole mass spectrometer platforms), associated supplies (polypropylene vials, screw caps, SPE cartridges), and broader laboratory testing services for water quality, wastewater, and forensic analysis. The issuing bodies span municipal and county government—the City of Tucson (Pima County, Arizona), the City of Palm Bay (Brevard County, Florida), and Brazoria County, Texas—representing both dedicated water utility departments and law enforcement forensic laboratories.
