UNSPSC 41115419: Circular dichroism spectrometer

A device for analyzing the molecular structure of an optically active substance by applying the electromagnetic field to linearly polarized light to generate left-handed and right-handed circularly polarized light and using the difference in molar extinction coefficient generated when circularly polarized light is passed through the sample.

UNSPSC 41115419 Circular dichroism spectrometer is a Commodity code that in recent state and local activity covers laboratory analytical instrumentation for public health, university research, and scientific testing — not narrowly circular dichroism devices alone, but the broader category of precision spectroscopy and chromatography equipment used in clinical and environmental labs. The code sees solicitation from county public health departments, university procurement offices, and special-purpose research institutions. Work under this code ranges from gas chromatography–mass spectrometry (GC-MS) equipment for chemical analysis to lab information management systems (LIMS) that support the operational workflows of public health laboratories.

Recent activity appears limited. The County of Santa Clara issued an RFI for a Public Health Lab Information Management Solution Replacement (posted April 7, 2026, response due April 22, 2026), framing a systems-integration play alongside hardware procurement. Lamar University in Texas solicited a Gas Chromatography Mass Spectrometer through IFB 734-11252025-AS with a December 19, 2025 deadline. A third opportunity — a Photoluminescence Spectrometer (ESBD posting, March 6, 2026) — lacks sufficient detail to assess scope or issuing body. Texas and California show the most recent activity; the code's geographic spread remains narrow and driven by academic and public-health-agency demand rather than broad municipal adoption. Vendors should monitor California county health systems and Texas higher-education procurement channels, where analytical-equipment refreshes and legacy-system replacements are driving near-term opportunity.
