Split-Stream Laser Ablation (LASS) Zircon Analysis

The contract encompasses high-precision laser ablation analysis of zircon grains using a split-stream LA-ICP-MS technique designed to concurrently collect uranium-lead isotopic data and trace element compositions. This method enables integrated geochronological and geochemical characterization of zircon samples, critical for accurately determining crystallization ages and interpreting petrogenetic processes in igneous and metamorphic rocks. The work requires advanced instrumentation, specialized expertise in laser ablation systems, and rigorous calibration protocols to ensure precise and reproducible results across both isotopic and elemental channels. The contract is classified as a subcontract under NAICS code 541620, indicating it falls within analytical services for scientific and technical consulting. It was posted on July 2, 2026, with a response deadline of July 8, 2026, and is administered by the Office of Acquisition Grants within the Department of the Interior. While specific performance location and point of contact details are not provided, the scope clearly demands a laboratory capable of operating split-stream LA-ICP-MS systems and meeting stringent analytical standards for geological materials. The absence of a set-aside designation suggests open competition for eligible subcontractors with proven capability in high-resolution geochronology and trace element analysis.
