Sought after DEPT OF DEFENSE DEPT OF THE ARMY AMC ACCACC-CTRSACC-APG -APG ADELPHI No Set aside used NT/REPAIR/REBUILD OF EQUIPMENT- INSTRUMENTS AND LABORATORY EQUIPMENT Precision Equipment Repair and Maintenance Performance Work Statement (PWS) Service Contract for NMR Spectrometer & Related Equipment

23 March 2026 C.1

Background Comprehensive service coverage is required to ensure continuous, uninterrupted operation of the Bruker Avance III 400 Megahertz (MHz) Nuclear Magnetic Resonance Spectrometer (NMR), in service at the Weapons and Materials Research Directorate of the Army Research Lab (ARL), Aberdeen Proving Ground (APG), MD. The system is equipped with broadband probes and ancillary hardware and electronics to permit acquisition of both liquids and solid samples (i.e. magic-angle spinning, or MAS). C.2

Objective The NMR system is used daily by a wide variety of programs and projects, primarily to assess the outcomes of material or chemical synthesis efforts. With multiple users on any given day, a period without access to the NMR would hinder multiple research programs. A service plan is required to ensure the continued operation of the NMR, to ensure timely performance of routine maintenance, to ensure timely completion of cryogen fills, and to ensure proper function of both the liquids and solids probes. C.3 Requirement The respondent shall provide service and maintenance coverage of the indicated NMR system, (Serial Number # 10215255), and all associated hardware, electronics, accessories, and probes. C.3.1: The contractor shall provide routine maintenance of NMR magnet, electronics, accessories, probes, and other related items; replace consumables such as filters at recommended intervals. This includes at least one performance maintenance (PM) visit each year of coverage. C.3.2: The contractor shall provide a technician or engineer to assist with liquid cryogen (liquid He) fills as necessary, defined as liquid He level at 50% or less. A typical fill interval is every ~4.5 months, meaning that up to three (3) fills may be required in any contract term. ARL is responsible for providing the cryogen. Weekly fills of liquid nitrogen are to be handled by ARL staff. C.3.3: The contractor shall be responsible for re-energization and setup of magnets in case of a quench event. C.3.4: The contractor shall provide on-site (APG) diagnostics and instrument service in case of performance degradation or component failure. Remedies may include component repair/refurbishment or component replacement as needed. C.3.5: The contractor shall provide service for probes, when necessary, either on-site (APG) or at the provider’s facility. C.4 AT-OPSEC

Requirements C.4.1: Access and general protection/security policy and procedures. This standard language is for contractor employees with an area of performance within Army controlled installation, facility, or area. Contractor and all associated sub-contractors employees shall provide all information required for

background checks to meet installation access
