LSJ Redacted_Redacted.pdf

This is a Limited Source Justification and Approval (LSJ) document for a federal procurement action dated 23 April 2026. The document authorizes the issuance of a firm fixed price contract for maintenance services on a brand name basis for an Aztec/mics/xstream/xmax80 analytical system, specifically Serial Number SC39432/39432. The requirement involves a comprehensive service and maintenance agreement for specialized hardware and software manufactured exclusively by Oxford Instruments.

The justification is based on FAR 8.405-6(b)(1), which permits procurement from a single source when an item is peculiar to one manufacturer. The agency determined that Oxford Instruments America Inc. is the only source capable of satisfying the requirement, as no other schedule holders can provide the necessary proprietary software support or OEM-certified parts required to maintain the equipment's operational resolution and data integrity. Market research confirmed this single-source determination. The document establishes that the contracting officer will conduct price analysis to ensure fair and reasonable pricing representing best value. No acquisition plan is required as the action falls below DFARS 207.103 thresholds. The LSJ includes technical cognizance certification and requires contracting officer certification of the justification's accuracy, with additional review and approval requirements dependent on the final contract value.
