Assay Technology Inc.

Assay Technology Inc., doing business as Assay Technology, manufactures and analyzes environmental monitoring equipment and sampling stations for the federal government as a prime contractor, competing exclusively full-and-open with no small-business set-aside designations across its portfolio. The company, a for-profit Subchapter S corporation headquartered in Livermore, California, specializes in 5-disk and 6-disk diffusive sampling stations, passive chemical dosimeters, and analytical services supporting federal agencies' atmospheric health assessment and occupational hygiene programs.

Assay Technology operates almost entirely as a prime contractor (100% of awards), with a single recent subcontract to Hanford Tank Waste Operations & Closure LLC for nitrous oxide badges and analysis under the Integrated Tank Disposition Contract. The company's customer concentration is extreme: the Department of the Navy's Bureau of Medicine and Surgery accounts for 96 awards and $16.8 million of the combined $17.9 million in potential value across 220 total awards—a 94% concentration by dollars. The Bureau anchors Assay Technology's primary federal relationship through the Navy's Submarine Atmosphere Health Assessment Program, which relies on Assay Technology's manufacturing and analysis of sampling stations for submarine environmental monitoring and worker breathing-zone assessment. Secondary customers include the Centers for Disease Control and Prevention Pittsburgh (17 awards, $396 thousand), the Office of Naval Research (8 awards, $270 thousand), the Army Materiel Command Research Development and Engineering Command (6 awards, $177 thousand), and the CDC Spokane Research Laboratory (4 awards, $90 thousand). The top four customers account for 99% of combined potential value.

Assay Technology holds a $6.7 million single-award Indefinite Delivery Contract with the Navy's Bureau of Medicine and Surgery running through November 21, 2028, which authorizes supply of up to 1,250 custom passive chemical dosimeters annually with three-week delivery and analysis turnaround requirements. The contract has generated 50 delivery orders ranging from $4,104 to $37,252 for 6-disk sampling stations, station analysis, and related equipment. Recent prime awards include a $37,252 delivery order in March 2026 for 134 six-disk sampling stations in support of submarine atmosphere monitoring, a $21,276 delivery order in December 2025 for sampling station analysis, and a $25,574 purchase order from the Occupational Safety and Health Administration in September 2025 for a flow-temperature-humidity control system at the OSHA Technical Center in Sandy, Utah. Additional vehicle holdings include Indefinite Delivery Contracts N6264518D5054 (26 task orders, $497 thousand) and N0018924DZ009 (16 task orders, $244 thousand), both supporting Navy health assessment operations.

The vendor's capability portfolio concentrates on testing laboratory services and environmental control device manufacturing per NAICS; the top five NAICS categories account for 139 of 220 awards, with Testing Laboratories and Services (84 awards) and Other Measuring and Controlling Device Manufacturing (41 awards) anchoring the footprint. By PSC, Assay Technology dominates Hazard-Detecting Instruments and Apparatus (95 awards) and Laboratory Equipment and Supplies (20 awards). Activity has grown modestly—three awards in 2022 to ten in 2025—with two awards in 2026 to date. Combined dollars obligated total $2.5 million against $17.9 million in potential value (14% obligated), indicating a pipeline of unstarted work; fourteen awards face completion inside the next twenty-four months, presenting recompete exposure for Assay Technology and opportunity for competitors entering submarine atmosphere monitoring or federal occupational hygiene testing.
