NIGP 28730: Detectors (Electron, Photon) and Detector Arrays

NIGP 28730 Detectors (Electron, Photon) and Detector Arrays, an Item code, encompasses specialized detection and measurement equipment procured by state and local agencies for environmental monitoring, health and safety compliance, and law enforcement applications. Recent state and local solicitations under this code reflect demand for high-purity germanium gamma detectors, law enforcement sensor and imaging systems, and battery backup detection or monitoring components—products that represent the technical instrumentation side of state and local procurement rather than commodity-level supplies. Issuing bodies include state health departments, state purchasing divisions acting on behalf of human services agencies, and multi-jurisdictional cooperative purchasing vehicles serving counties and law enforcement entities across multiple states.

The Texas Health and Human Services Commission (HHSC) issued IFB HHS0017273 in June 2026 for eight Mirion Technologies high-purity germanium coaxial detectors, with responses due June 23, 2026, to support radiochemical drinking water monitoring and environmental surveillance around nuclear facilities—a representative example of the radiation detection work state environmental and health agencies buy under this code. Sourcewell, a Minnesota cooperative purchasing vehicle, posted RFP 061626 in May 2026 to establish a law enforcement equipment contracting solution available to county sheriff's offices, city police departments, school districts, and other public entities across Washington state and nationwide, with responses due June 16, 2026. The State of Nevada Purchasing Division solicited battery backup system quotes through its EcoFlow procurement in April 2026 on behalf of the Nevada Department of Human Services, with a May 27, 2026 deadline. Recent activity spans the upper plains (Minnesota, Washington, Nevada) and Texas, with issuing bodies ranging from state health and human services departments to regional cooperative purchasing consortia serving multiple jurisdictions.
