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.

Capabilities

Quality Assurance

When product quality is on the line — whether you're troubleshooting a failure, qualifying a raw material, or meeting a critical compliance deadline — you need results you can trust from a lab with nothing to sell you but the truth.

RJ Lee Group provides independent, third-party quality assurance testing and failure analysis for manufacturers, contractors, suppliers, and regulatory bodies across a wide range of industries. Our scientists don't just run tests—they interpret results, identify root causes, and deliver actionable insights that help you make better decisions faster.

With over 40 years of materials science expertise, nationally accredited laboratories, and one of the most diverse analytical instrument portfolios in the country, we bring the depth and rigor your quality program demands—whether you're resolving a single product defect or building a long-term QC partnership.

Quality Control Testing That Finds Problems Before They Become Failures


Quality issues rarely announce themselves—until they affect performance, schedules, or reputation. Clients engage quality control and quality assurance testing services to answer critical questions about their materials, processes, and products. From routine verification to targeted investigations, independent testing helps identify risks, confirm specifications, and support decisions across a wide range of applications.

  • Raw Material Qualification
    Verify that incoming materials meet your specifications before they enter production.

  • In-Process Quality Control
    Monitor critical stages of manufacturing to catch deviations early and reduce scrap

  • Finished Product Testing
    Confirm that your final product meets performance standards, regulatory requirements, and customer expectations.

  • Failure Analysis & Root Cause Investigation
    When something goes wrong, our scientists identify the underlying cause and recommend corrective     actions.

  • Regulatory Compliance Testing
    Navigate evolving standards with testing programs designed around your industry's requirements.

  • Third-Party Verification & Litigation Support
    Independent evaluations that hold up under legal and regulatory scrutiny.

Not all QA laboratories are created equal. Here's what sets us apart.

  • Scientist-Led Analysis, Not Just Data
    Many labs hand you a report full of numbers. Our team of Ph.D.-level scientists and senior materials specialists interpret those numbers in context, identifying not just what happened, but why it happened and what to do about it. You get answers, not just data points.

  • Independence You Can Rely On
    As a third-party laboratory with no ties to manufacturers or suppliers, our findings carry the credibility that regulators, legal teams, and stakeholders demand. Our data has supported litigation, warranty claims, and regulatory submissions for nearly four decades.

  • One of the Broadest Analytical Toolkits in the Industry
    From electron microscopy and X-ray diffraction to mass spectrometry and thermal analysis, our laboratories house an extensive range of instrumentation under one roof. That means fewer delays from outsourcing, faster turnaround, and the ability to cross-correlate results across multiple techniques for a more complete picture.

  • Nationally Accredited, Globally Trusted
    Our laboratories hold accreditations from A2LA, NVLAP, AIHA LAP, AASHTO, and numerous state and federal programs, including DoD ELAP and DOECAP. When your quality data needs to hold up under scrutiny, our credentials back it up.

  • Responsive, Deadline-Driven Service
    Quality issues don't wait, and neither do we. Our team works within your timeline, whether that's a routine testing schedule or an urgent failure investigation, and keeps you informed throughout the process.

FTIR 1

Instrument Spotlight

Fourier Transform Infrared Spectroscopy (FTIR) 

FTIR is one of the most versatile and widely used analytical tools in quality control testing. It works by passing infrared light through a sample and measuring how the material absorbs specific wavelengths. Since every compound produces a unique absorption pattern — essentially a molecular fingerprint — FTIR can rapidly identify a material, verify that it meets a known specification, or detect unexpected contaminants.

In a QC environment, FTIR is commonly used to confirm incoming raw materials match supplier certificates, identify unknown residues or surface contamination, verify polymer and additive composition, analyze coatings and thin films, and compare "good" versus "failed" samples to pinpoint compositional differences. Our scientists don't just collect spectra; they interpret them in the context of your material, your process, and your problem.

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.
