The Department of Energy, through ORNL UT-Battelle LLC, is seeking proposals for the procurement of two High Resolution Compact Portable Mass Spectrometers, specifically the Kanomax InfiTOF-II or an equivalent model. The mass spectrometers must meet critical specifications, including the capability for gas phase sample introduction, a resolution exceeding 2,500 (m/Δm) for distinguishing between similar atomic masses, and a mass range of at least 800 m/z, all while maintaining a compact footprint of less than 1m x 1m. This procurement is essential for enhancing analytical capabilities in research or clinical settings, emphasizing precision and space efficiency. Interested vendors should refer to the attached Bill of Materials for detailed proposal requirements and may contact Ben Spry at sprybl@ornl.gov or 865-341-2750 for further information.
