PARTICLE INSTRUMENTS LLC

Particle Instruments LLC specializes in the design, integration, and support of high-resolution particulate matter analysis systems, with deep expertise in Dekati’s Electrical Low Pressure Impactor (ELPI+) and related instrumentation. The company delivers advanced hardware and software solutions for real-time particle size distribution measurement, including critical upgrades to sensor electronics, data acquisition systems, and vacuum subsystems such as dry scroll pumps. Their technical focus centers on precision aerosol characterization, enabling regulatory-grade air quality monitoring and research-grade environmental sampling. Differentiators include seamless system integration of legacy and next-generation instrumentation, compliance with stringent federal analytical standards, and rapid procurement support for mission-critical instrumentation under non-availability waivers. The contractor maintains consistent engagement with the Environmental Protection Agency, providing specialized particle sampling systems for ambient air monitoring and source apportionment studies. They also support the National Aeronautics and Space Administration with instrument upgrades for atmospheric research applications and deliver equipment to the Department of Health and Human Services for laboratory-based exposure assessment. These relationships reflect a pattern of trusted technical partnership, particularly around complex, non-commercial instrumentation requiring customization and regulatory alignment. Operating under NAICS 334516, Particle Instruments LLC is positioned as a niche manufacturer and integrator of analytical laboratory instruments for aerosol science. Their market focus is on environmental monitoring, atmospheric research, and public health surveillance—sectors demanding high-fidelity, field-deployable particulate measurement systems. They serve a specialized vertical where off-the-shelf solutions are inadequate, and system-level engineering is essential. As a small business structured as 2J and headquartered in Saint Paul, Minnesota, Particle Instruments LLC operates without federal certifications but maintains a focused presence in the federal scientific procurement market. Their geographic location supports regional logistics for federal laboratories and research institutions across the Upper Midwest and beyond.
