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:

PFAS Lab Testing and Analysis

Coming Soon! RJ Lee Group will help clients and municipalities with PFAS Regulations, Pre-Screening, and Manufacturer Consulting. We are building PFAS testing capability and capacity, and anticipate taking samples in Q1 2023.

Traces of PFAS have been found in water, air, and soil in a wide variety of geographic locales. There is limited data, but extensive speculation about the health implications of PFAS exposure. Exposure to PFAS has been claimed to cause cancer, high cholesterol, liver damage, and thyroid disease, among other impacts. PFAS has been found in some foods, packaging, cookware, adhesives, sealants, fabrics, fire fighting foams, and cosmetic products.

Targeted Analysis with LC-MS/MS

RJ Lee Group is building capacity to analyze samples for PFAS constituents following several established methods including:

  • EPA 533
  • EPA 537 Rev. 1.1
  • ASTM D7979 with Isotopic Dilution
  • ASTM D7968-17

These are targeted methods for determining concentrations of specific PFAS compounds, such as PFOA and PFOS. Over 20 PFAS chemicals can be targeted. Fill out our form below to discuss your testing situation, or discuss how we can soon help.

Targeted Analysis with LC-MS/MS

Why Our Customers Choose Us?

Standard 24-48 hour turnaround times


Detection limits below method requirements

Long experience in producing legally defensible data

Developing groundwater sampling technique for superior accuracy

Partnered with one of the largest global analytical instrument makers for state-of-the-art capabilities

Method Development and Consulting

Our scientists aim to help lower PFAS detection limits and find new, cheaper and faster pre- screening methods. RJ Lee Group scientists are working with industry leaders and regulators to develop methods for improved analysis. RJ Lee Group provides a 360 degree approach to data interpretation including identification of potential sources and data integration with other relevant environmental analyses.

Untargeted Analysis with LC-MS-TOF

Identification of Unknowns

Detection of PFAS compounds not specifically targeted by ASTM or EPA methods.

Chemical Fingerprinting

Evaluation of detected constituents beyond targeted PFAS compounds can be used to identify or eliminate potential sources.

PFAS is an Emerging Contaminant of Interest for Air Quality

PFAS in the atmosphere can be carried long distances before deposition onto land and water.

RJ Lee Group will soon perform sampling for PFAS in the air. Sample collection is performed on solid media and analysis is done with LC-MS/MS test methods. We anticipate being ready for samples in Q1 2023.
