JUSTIFICATION FOR SOLE SOURCE PROCUREMENT (OPEN MARKET OR GSA)

UNDER $350,000

Sole source acquisitions may be used on a limited basis and only when the Contracting Officer’s Representative (COR)/Program Official has provided sufficient justification and the Contracting Officer has determined that the circumstances warrant such action. The content for a justification must contain detailed facts and rationale to justify the sole source acquisition. Soliciting from a single source must be done in accordance with FAR 12.102, 12.201-1 or 8.401 (GSAR 538.7104-3). At a minimum, the following information must be included:

Identification of Program Office, Contracting Activity, and Proposed Requirement, Justification and Program Office Certification:

3. Is the requirement on GSA Schedule? � Yes � No

If yes, provide schedule number: Click here to enter text.

Rev. 6/2/26 result in duplication of effort, increased cost, and lack of consistency with stakeholder instrumentation. Therefore, non-Thermo instruments do not meet the Government’s requirement for compatibility, continuity, and support of existing and future research and stakeholder needs

3. Facts supporting sole source procurement: What can this product/service do that other products/services cannot do? The Nicolet Summit X FTIR spectrometer from Thermo

Electron North America LLC is required to support the Rapid Quartz Analysis (RQA) monitoring approach developed by the National Institute for Occupational Safety and Health.

This method relies on Fourier Transform Infrared spectroscopy for measurement of respirable crystalline silica in mine dust samples and is used to support mine operators in protecting workers from exposure. The Summit X FTIR is required due to compatibility with existing and future Thermo instrumentation platforms used by stakeholders implementing the RQA method. The National Institute for Occupational

Safety and Health has developed data processing tools and workflows specific to

Thermo FTIR systems. These tools are not compatible with newer Thermo software platforms unless updated instrumentation is available. Additionally, the program’s existing Thermo FTIR instruments are legacy models that are no longer fully supported by the manufacturer and will reach end-of-life within approximately four years. Continued use of outdated instruments limits the ability to maintain method compatibility, support stakeholders, and ensure continuity of research. Acquisition of the Summit X FTIR ensures compatibility with current software, supports method development, and aligns with instrumentation being adopted by external stakeholders.

E. Program Office Certification:

I have reviewed this sole source justification and certify the justification is true and accurate to the best of my knowledge and adequate to support other than full and open competition.
