The U.S. Geological Survey Office of Acquisitions and Grants is seeking maintenance services for a Thermo Scientific Argus VI Noble Gas Mass Spectrometer located at the Denver Argon Geochronology Laboratory. The contractor must provide one annual preventative maintenance site visit, on-demand emergency repairs with a targeted three-business-day response time, factory-certified replacement parts, and priority technical support to maintain the instrument within manufacturer specifications. The service contract includes a base period from September 20, 2025 to September 19, 2026, with an optional six-month extension through March 19, 2027. The procurement will be awarded to the lowest-priced, technically acceptable offeror, with the government reviewing proposed pricing for technical conformance and reasonableness. The original quotation deadline was September 11, 2025 at 12:00 PM Mountain Time, but an amendment extended the close date to September 12, 2025 at 5:00 PM Mountain Time, with submissions required via email to Jenn Rollin at jrollin@usgs.gov.

This solicitation was initially designated as a Total Small Business set-aside but was subsequently amended to dissolve the set-aside and reopen for full and open competition.

The contract covers maintenance of a single specialized scientific instrument with performance focused on minimizing downtime and ensuring consistent laboratory operations. Work will be performed at the USGS Denver Argon Geochronology Laboratory, with the contractor required to provide all necessary plant, equipment, labor, supervision, and materials for the maintenance services.
