Major Element Geochemical Analysis – Fusion/XRF

The contract seeks a subcontractor to perform major element geochemical analysis using lithium metaborate fusion combined with X-ray fluorescence spectroscopy, a precise method for determining the quantitative composition of geological samples. This method involves melting sample material with lithium metaborate to form a homogeneous glass bead, which is then analyzed via XRF to accurately measure concentrations of key oxides such as silica, alumina, iron oxide, and other major elements. The work is classified under NAICS code 541380, indicating it falls within scientific and technical consulting services, specifically analytical chemistry services. Performance of the work is not geographically restricted, and the solicitation was posted on July 21, 2026, with responses required by July 25, 2026. The contracting entity is the Office of Acquisition Grants under the Department of the Interior, though no specific point of contact or detailed location for performance is provided. The subcontract nature implies the selected vendor will operate under the authority of a prime contractor or broader programmatic framework managed by the federal agency.
