NIGP 49346: Ion Chromatographs, Including Parts and Accessories

NIGP 49346 Ion Chromatographs, Including Parts And Accessories is an Item code under which state and local governments procure analytical instrumentation and related consumables for environmental and water quality testing. Recent solicitations show purchasing of complete ion chromatograph systems for materials testing and laboratory operations, alongside specialized consumables such as cartridges and vials required for specific analytical workflows like PFAS and dioxane detection in drinking water. Issuing bodies include state departments of transportation, county public health agencies, and municipal water utilities, each with distinct analytical missions ranging from materials characterization to environmental compliance monitoring.

Activity under this code spans multiple states and regions. The Texas Department of Transportation posted a solicitation for a complete ion chromatograph system in April 2026 (IFB 601440000052016, response deadline March 30, 2026), while the County of Santa Clara issued a Request for Information in April 2026 (RFITSSFY260686, response deadline April 22, 2026) for a lab information management system to support public health laboratory operations that would include chromatography and related analytical capabilities. The City of Tucson, Arizona solicited Waters Technologies brand consumables for PFAS and dioxane analysis through IFB 240045, structured as a one-year contract with four one-year renewal options and including mandatory pre-submittal conference attendance. Vendors responding to municipal water utility procurements should expect federal set-aside compliance requirements — the Tucson opportunity carried HUD Section 3 Program guidelines with 25 percent labor hour requirements for Section 3 workers.
