NIGP 19397: X-Ray Contrast Media: Barium, Sulfate, Dyes, etc.

NIGP 19397 X-Ray Contrast Media: Barium, Sulfate, Dyes, Etc., an Item code, encompasses maintenance and repair services for specialized X-ray inspection systems and chemical supply contracts for copper sulfate in both crystal and liquid forms that state and local governments procure on an as-needed basis. The code captures two distinct categories of work: highly specialized inspection and repair services for proprietary X-ray equipment used in airport security and similar applications, and routine chemical supply contracts for industrial or operational uses of copper sulfate compounds. Issuing bodies include county aviation departments, county facilities and operations departments, and other local jurisdictions with security screening or water treatment infrastructure.

The two most recent opportunities posted in June 2026 reflect this split. Broward County Aviation Department issued an RFI (BLD2132311F1) due July 28, 2026, to determine whether maintenance services for Rapiscan 600 series, 900 series, VOTI XR3D, and Gemini X-ray inspection systems are available from vendors other than the exclusive manufacturer, or whether comparable alternate systems exist—work characterized as highly specialized and involving complex X-ray technology. Pasco County, Florida posted an indefinite-quantity RFQ (RFQFP261004) due June 26, 2026, to supply large copper sulfate crystals and liquid copper sulfate on an as-needed basis with one or more vendors. Activity under the code concentrates in Florida, with representation from county-level purchasing offices and special-purpose districts managing transportation, security, and utilities infrastructure.
