The Department of the Treasury, specifically the Bureau of the Fiscal Service, intends to award a sole source contract to AB Sciex, LLC for the renewal of an Assurance Plan and continuous service for existing equipment, including one preventive maintenance (PM) service for the SCIEX QTrap 5500+ and Excion LC system. This procurement is critical as AB Sciex is the exclusive manufacturer of the SCIEX branded mass spectrometers and related equipment, ensuring that only their trained engineers can provide the necessary maintenance and support, which includes genuine parts and a guaranteed response time for repairs. Interested parties must submit their qualifications and capability statements by 10:00 AM ET on December 13, 2024, to be considered, as no solicitation will be made available and responses must be sent electronically to the designated email address.
