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:

RJLG Materials Insights

The articles on this page represent a renewed endeavor among our multi-disciplinary scientific staff, providing a technical resource to our clients (existing and prospective) on a wide variety of materials behavior. Each internally peer-reviewed article is written by RJLG scientific staff based on our knowledge, training, and experience serving the analytical and consultative needs of diverse industries, both domestically and internationally. We acknowledge that the topics discussed here are frequently more complex and nuanced than can be covered in a short article, but it is our hope that the information provided will prove useful to the reader in understanding an array of materials phenomena, and convey some of the breadth and depth of knowledge and experience that RJLG applies to industrial problem solving and root cause analysis. New topics will be added on a regular basis so check back frequently or sign up for RJLG Materials Insights alerts.

We invite you to call 1.800.860.1775 for more information, or to get in contact with one of our scientific staff who can assist you in your project. We hope you enjoy this resource and find it useful.

Nuisance Dust Damage Claims

A broad spectrum of industrial operations, naturally occurring sources, and vehicular emissions has the potential to generate particulate that – if not properly contained – can be cause for environmental or health concerns. A combination of engineering controls and ongoing monitoring are typically deployed to ensure compliance with limits

The Characterization Advantage of Electron Backscatter Diffraction (EBSD) Microscopy

Electron backscatter diffraction (EBSD) microscopy is a characterization technique used with scanning electron microscopes (SEMs) for determination of crystallographic information present in both metal and mineral samples. Much like energy dispersive X-ray spectroscopy (EDS), which provides the elemental composition through the interaction of electron beam and individual atoms, EBSD uses

Nondestructive Evaluation (NDE) of Concrete with UPV

Ultrasonic pulse velocity (UPV) is an acoustic non-destructive test (NDT) method most often used to evaluate the relative quality, or uniformity, of concrete structures, and to identify the presence of internal flaws such as cracks, voids, and honeycombing. UPV can also be used to assess the severity of damage

Predicting the Thermal Maturity of Shale

Geochemists exploring potential hydrocarbon production from source rock must be able to accurately predict the type and relative abundance of each type of hydrocarbon that is present prior to investing resources in the material’s extraction.  Many chemical and physical factors contribute to hydrocarbon formation, so hydrocarbon predictions are typically

Environmental Stress Cracking in Plastics

Environmental stress cracking (ESC) is a well-documented phenomenon in plastic/polymer components and can occur when a polymer component is exposed to an aggressive chemical agent while under tensile stress, whether residual or applied. Also referred to as environmental stress crazing, this process is analogous to stress corrosion cracking (SCC)

Iron Sulfides in Concrete

Oxidation of Iron Sulfide Minerals Iron sulfides are accessory minerals found in a variety of rock types, with pyrite (FeS2) and pyrrhotite (Fe1-xS) (x = 0 to 0.2), being most common.  Under some conditions, these minerals can undergo oxidation reactions that have the potential to cause damage to concrete pavement

Alkali-Silica Reaction

Alkali-silica reaction (ASR) is a common cause of premature concrete deterioration, resulting in expansion and cracking of concrete elements. ASR is a chemical reaction between alkali hydroxides in the pore solution of concrete and certain siliceous (silica-bearing) rocks and minerals present in some concrete aggregates. The result is the

Stress Corrosion Cracking

Stress corrosion cracking (SCC) is an environmentally-driven failure mechanism that can be found in metal alloys of all types including pure metals, though pure copper is thought to be immune to SCC. Ceramics and polymers also exhibit forms of environmentally induced crack propagation; however, the focus of the present
