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:

Welcome to RJ Lee Group 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.
