UNSPSC 41113625: Ionization chambers

UNSPSC 41113625 Ionization chambers is a Commodity code covering radiation detection equipment, specifically sensor-based detector systems and instruments that measure ionizing radiation. Recent state and local solicitations show purchasing focused on specialized detector hardware with precise sensing capabilities—including pixelated semiconductor detectors and broadband radiation detection instruments meeting defined technical and calibration standards. Issuing bodies are primarily higher-education institutions and state-level procurement offices. Texas A&M University Division of Finance Procurement Services and the State of California Department of General Services each appear in the recent record, indicating that universities and state purchasing authorities are the main buyers under this code.

Activity is concentrated in Texas and California. Texas A&M University posted an ITB for a MiniPIX TPX3 detector with 500 μm Si sensor on July 13, 2026, with responses due July 27, 2026 through the AggieBid portal; the California Department of General Services issued RFB-IS-26201063 for radiation detectors on June 17, 2026, with bids due June 30, 2026, subject to California's Certified Business Enterprise (CBE) requirement and best-value evaluation of price and technical merit. The California procurement emphasizes compliance with state and federal regulations, calibration accuracy, warranty and maintenance provisions, and unit pricing. Both opportunities indicate that bidders must demonstrate technical capability and familiarity with specialized detector specifications and regulatory requirements.
