The Department of Energy's National Energy Technology Laboratory (NETL) intends to award a sole source contract for the renewal of a Preventative Service Maintenance Agreement for specific LECO analytical instruments. The procurement involves maintenance services for the LECO RHEN602 hydrogen analyzer, LECO CS744 carbon/sulfur combustion analyzer, and LECO ON736 oxygen/nitrogen inert gas fusion analyzer, which require exact replacement parts from the original equipment manufacturer (OEM) to ensure reliable operation. This maintenance is critical for the continued satisfactory performance of these specialized instruments, as LECO possesses the proprietary knowledge necessary for their operation and maintenance. Interested parties who believe they can meet these requirements must submit their capabilities in writing to Rebekah Parks at rebekah.parks@netl.doe.gov by 3:00 PM ET on November 14, 2024, as this notice is not a request for proposals.
