The Department of Defense, specifically the Department of the Army, is seeking to award a single-source service contract for annual preventative maintenance and repairs on two Agilent spectrometers at the Red River Army Depot in Texarkana, Texas. The contract will cover maintenance for the Agilent 900 Mass Spectrometer (MS) and the Agilent 5800 Optical Emissions Spectrometer (OES), which are critical for analytical laboratory operations. Due to the proprietary nature of Agilent's replacement parts and technical data, the procurement will be conducted non-competitively under the authority of 10 U.S.C. 2304(c)(1). Interested parties may direct inquiries to Vanessa Buster at vanessa.k.buster.civ@army.mil or call 571-588-1506 for further information.
