Ion-Tof Usa, Inc.

Ion-Tof USA Inc., headquartered in Spring Valley, New York, operates as a sole-source prime contractor specializing in maintenance, repair, and user training for time-of-flight secondary ion mass spectrometers (SIMS5 and related instruments) to the Department of the Navy, Department of the Air Force, and the National Institute of Standards and Technology. The company competes full-and-open with no small business set-asides across its federal footprint and holds proprietary technical knowledge and exclusive access to schematics and data that drive repeated sole-source awards from defense and scientific agencies.

Ion-Tof USA's customer concentration is narrow but recurring. The Department of the Navy Naval Sea Systems Command leads by combined potential value at $1.8 million across five awards, followed closely by the National Institute of Standards and Technology at $917 thousand across thirteen awards. The Department of the Navy Strategic Systems Programs account for $249 thousand across six awards. These three agencies represent 63% of recent awards by count and 90% of combined potential value. The Navy's two components (Naval Sea Systems Command and Strategic Systems Programs) collectively anchor the vendor's defense footprint; NIST dominates by award frequency but with smaller individual contract values, reflecting the vendor's role in maintaining analytical equipment across federal research laboratories and military metrology facilities. Smithsonian Institution ($76 thousand, four awards) and the Department of the Air Force ($44 thousand, three awards) round out the active customer set.

Ion-Tof USA's award portfolio clusters around SIMS5 maintenance and related preventative-maintenance work. Representative recent awards include a $69.1 thousand purchase order from Naval Strategic Systems Programs for maintenance of SIMS 5 and M6 instruments and the vacuum option (January 2026, through December 2026, performed in Crane, Indiana); a $63.9 thousand sole-source purchase order from Naval Sea Systems Command for SIMS5 mass spectrometer maintenance including preventative maintenance, equipment repairs, and user training (December 2023, through December 2024); and a $63.9 thousand purchase order from the Department of Defense Washington Headquarters Service for mass spectrometer maintenance services at the Crane facility (January 2025, through January 2026). A smaller $9.45 thousand award from Naval Sea Systems Command in December 2021 covered TOFSIMS V training. The primary NAICS concentration is Analytical Laboratory Instrument Manufacturing (24 awards) and Other Electronic and Precision Equipment Repair and Maintenance (14 awards); PSC coding runs to Maint/Repair/Rebuild Of Equipment- Instruments And Laboratory Equipment (20 awards) and Laboratory Equipment And Supplies (17 awards).

Activity has been sparse and episodic: two awards in 2021, one in 2022, two in 2023, none in 2024, one in 2025, and one in 2026, with total combined potential value of $3.5 million across 49 awards since 2004. The vendor operates as a prime on 100% of recent awards with no subcontract footprint. One award carries an ultimate completion date within the next twenty-four months ($69 thousand), representing minimal recompete exposure in that window. Combined dollars obligated across all awards ($4.5 million) exceed combined potential value ($3.5 million), indicating historical overruns or scope additions on maintenance purchase orders.
