The University of Mississippi's Procurement Services is announcing a sole source purchase for an upgrade to a Spectral Evolution OreXpress spectrometer to RS-3500 configuration, with objections due September 28, 2026 at 10:00 a.m. Central Time. This is a sole source procurement — only Spectral Evolution, Inc., the exclusive U.S. manufacturer with no authorized domestic distributors or external service centers, can perform the required upgrade using proprietary procedures necessary for compatibility and authorized conversion.

The Department of Geology & Geological Engineering seeks to upgrade its existing Spectral Evolution OreXpress spectrometer (Serial No. 252-8020) to an RS-3500 spectroradiometer. The scope includes manufacturer-authorized conversion, inspection, spectral calibration, recalibration, and associated maintenance and refurbishment services performed by the manufacturer.

The total estimated purchase amount is $14,549.03, which incorporates a negotiated 3% academic discount applied to the manufacturer's service charges.

Interested parties may object to the sole source certification by submitting detailed objection statements, contact information, company details, and a statement of capabilities to perform the required services or products. Objections must be submitted to Jeff Wells, Procurement Manager, at the University of Mississippi Procurement Services by hand delivery, mail, overnight delivery, or email at solesource@olemiss.edu with a copy to purchase@olemiss.edu. All submissions must reference sole source number SS 494.
