This is a notice of intent, and not a solicitation, for the Department of the Army to award a sole‑source, Firm‑Fixed‑Price (FFP) Indefinite Delivery Indefinite Quantity (IDIQ) contract vehicle to:

Is compatible with the currently fielded MSD analyzer workflow and associated proprietary consumables/software architecture; and
Supports continuity of operations, training, and logistics for the existing user base.
