Sole source TQ-XS tandem MS maintenance

The U.S. Environmental Protection Agency Office of Water is seeking a Firm-Fixed Price purchase order for a performance maintenance agreement to support a Waters TQ-XS Tandem Mass Spectrometer. The objective of this agreement is to maximize equipment uptime and productivity while eliminating the costs associated with unplanned maintenance and repairs. The contract is structured as a base year with four subsequent option years, resulting in a total period of performance of five years from the date of issuance. The agency intends to negotiate this requirement on a sole source basis with Waters Technologies Corporation, as the manufacturer is uniquely qualified to provide the necessary upgrades and services for this specific platform, which utilizes StepWave ion optics and TriVersa NanoMate-compatible sampling. This procurement falls under NAICS code 811210 for Electronic and Precision Equipment Repair and Maintenance. Interested parties were required to submit documentation electronically to the contract specialist by November 18, 2026.
