A History of Expertise and Innovation

RJ Lee Group has assessed environmental issues since the early 1980s when our Energy Technology Consultants (ETC) pioneered the recognition of specific air quality patterns. We developed a cutting-edge technique for identifying, measuring, and characterizing particles in the air using computer-controlled scanning electron microscopy (CCSEM).

RJ Lee Group has worked with clients in various industries, including the U.S. Environmental Protection Agency (EPA), to assess and provide solutions for environmental factors that could affect our health. Our services have grown over the years, from setting controls for unbound nanoparticles (UNP) to designing and building test chambers to simulate specific environmental conditions.

Today we offer our expertise for our clients’ environmental and compliance concerns and perform rigorous assessment and management of potential environmental risks.


Materials Characterization

RJ Lee Group's state-of-the art materials characterization laboratory is equipped with an extensive breadth of instrumentation and experience capable of evaluating the macro, meso, and microscale properties of a wide range of metals, polymers, and composites. We provide organizations with practical recommendations for critical materials decisions.

As materials and devices evolve in complexity, so must our analytical methods. RJ Lee Group boasts one of the world's largest collections of electron beam instruments, enabling us to visualize materials at both low magnification for surface surveys and ultra-high magnification for nanoscale scrutiny.

How AeroTech Secured Its Future

When AeroTech Industries faced recurring defects in a crucial aircraft component, they were at risk of losing multi-million dollar contracts and jeopardizing the jobs of hundreds of employees. They enlisted the help of RJ Lee Group, who quickly deployed a team of technical experts. Through state-of-the-art forensic analysis, RJ Lee Group identified and rectified the root cause—a flaw in the casting process—eliminating the defect and preserving AeroTech's contracts.
