The U.S. Geological Survey (USGS) is conducting market research to identify qualified sources capable of providing in-situ laser-ablation split-stream (LASS) radiogenic isotope and trace element analysis services for geological research in Alaska. The procurement aims to secure access to a Laser-Ablation Split-Stream Multi-Collector Inductively Coupled Plasma Mass Spectrometer (LASS-MC-ICPMS) for U-Pb geochronology, Hf isotope, and trace element analysis on zircon samples, requiring six days of instrument operation, 24-hour access for USGS scientists, and continuous technical support from personnel with a Ph.D. in analytical geochemistry. Zircon's unique geochemical properties make it vital for understanding the petrogenetic history of igneous rocks, thereby enhancing geological insights. Interested parties must submit detailed capability statements by the specified deadlines, with the period of performance set from August 4, 2025, to December 31, 2026.
