We provide testing services to certify product and materials compliance, support quality control, and ensure the health and safety of workers and their environment. We provide assistance for clients who are not sure what tests they need. Our accredited materials characterization laboratory is the foundation of all the services of RJ Lee Group provides, including standardized testing for compliance, industrial hygiene and environmental analyses, quality control, and materials research and development.

We provide credentialed expertise supported by robust scientific data. We provide significant support to industrial clients for product development, industrial hygiene and overall production support.

RJ Lee Group maintains a visible and respected reputation within the legal community, having offered scientific support in civil litigation matters for nearly 30 years. 

  • Product Liability 
  • Toxic Tort
  • Construction Defect
  • Fugitive Emission
  • Personal Injury

  • Contract Disputes
  • Insurance Subrogation

Subject Matter Experts

From our core business of providing scientific solutions to our clients, we have developed innovative products. Some are produced internally, and some have arisen from partnerships with other research organizations. 

For example, we build lab software solutions to help manage and streamline your labs data, and environmental testing products for a variety of applications. 

  • IntelliSEM is a powerful automated particle analysis system.
  • ParticleID is  a customizable cloud hosted web application used to identify foreign particulate matter and  assist with root cause investigations. 

Other products we create count particles and help keep the air and environment safe.

RJ Lee Group is a materials analysis laboratory and consulting company which serves many different industries. We offer scientific solutions such as industrial forensics services, laboratory and testing services, litigation support, and laboratory software to many industries:

Industrial Hygiene

RJ Lee Group identifies, evaluates, analyzes, and suggests control measures for environmental elements that originate in the workplace and may cause potential source of risk to workers or the environment. We offer analytical and consultative industrial hygiene services in materials research and selection, environmental health and safety and quality control throughout the product life cycle.

Particulate Matter (PM)

Identifying particulate’s composition can lead to the source of particulate or contamination. When air quality concerns exist, identifying particulate size will reveal if it exceeds the criteria for respirable particulate matter (RPM). RJ Lee Group’s team of experts is familiar with industry standards and guidelines that ensure environmental safety and health, and we can assess potential negative impacts to determine where controls are necessary. This is especially important in industries that manufacture pharmaceuticals and electronic materials that may generate contaminants of concern down to the nano level. We observe manufacturing processes to uncover environmental or occupational issues and recommend changes to reduce potential exposure and contamination. Our expertise ranges from the regulatory demands of hospital pharmacy and clean room environments, to the characterization of aggregates and nuisance dust in the construction industry, to the monitoring of air in coal mines and examination of flyash from coal-burning plants.

Unbound Nanoparticles (UNP)

Unbound Nanoparticles can be man-made, or can occur incidentally in ambient air in the form of diesel and welding fumes and coal combustion. Natural sources, such as smog or fire, can also be cause for concern. Materials at the nanoscale level exhibit different properties than they do at the macro level. At the nano scale, their molecules tend to self-assemble and form new structures. We use electron microscopy, diffraction and spectroscopy techniques to measure size, determine morphology and agglomeration state, elemental composition and the structures of new materials at the nanoscale. RJ Lee Group is a leading edge contributor to nanoscale particulate studies and has successfully completed several monitoring projects for federal government and industry clients where the health and safety hazards as well as environmental impacts related to UNP were evaluated. We work in collaboration with industry, government and academia to characterize nanoparticles and to prepare for their regulation.

Monitoring and Sampling

RJ Lee Group has extensive practical experience in designing and implementing air sampling and monitoring plans to measure particulate matter, asbestos, dust, vapors, metals and crystalline silica, PCBs, PNAs and dioxins. We also perform environmental site assessments and source apportionment plans to determine the contributions of various pollution sources to a location of interest. We can help determine the best approach for monitoring particulate matter or vapors and aerosol particles including:

  • Indoor Air Quality (IAQ) and Workplace Monitoring (IEQ)
  • To meet EPA requirements
  • Assess personal exposure of workers to volatile compounds
  • To determine process pollutants
  • Environmental Monitoring
  • Source identification
  • Source apportionment
  • Nuisance dust monitoring
  • Simulation chambers
  • Product Labeling Information
  • Provide a controlled environment to establish product safety information such as generation rate and exposure impact for MSDS and information/warning labeling.



RJ Lee Group has offered a wide range of Industrial Hygiene Services for over 30 years. Our experts work with the manufacturing, mining, oil and gas, education, transportation, metals, environmental, and plastics industries, among many others.
