66--MicroXRF Geochemistry Sensor for attachment to Geotek MSCL-XZ II System

The U.S. Geological Survey (USGS) is conducting market research (Sources‑Sought) to identify qualified vendors capable of supplying a micro‑XRF geochemistry sensor for attachment to the existing Geotek MSCL‑XZ II (JHAWS) core‑logging system. The sensor must meet the minimum technical specifications: elemental detection from Al to U; a sealed Rh or Mo X‑ray tube operating 4‑50 kV at 15 W; a large‑area SDD detector with 133 eV resolution at Mn Kα; collimation of 0.5 mm (down‑core) and 5 mm (cross‑core); a helium‑flushed measurement cell for low‑energy elements; software providing full control of X‑ray settings, filter selection, spectral fitting, and elemental mapping; and full mechanical and software compatibility with the Geotek MSCL‑XZ II platform. The unit must run on standard laboratory power (no external chiller) and be installed on‑site by qualified Geotek technicians. Responses (product data sheets demonstrating compliance with the technical specifications) are to be submitted by email to yangzhi_deng@ios.doi.gov no later than 09:00 PST on 28 April 2026. This is a market‑research effort only; no contract award is guaranteed and the Government will not reimburse response costs. NAICS 334516 (Analytical Laboratory Instrument) and PSC 6640 (Laboratory Equipment and Supplies) apply.
