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:


Intelligent Scanning Electron Microscope Analysis

The IntelliSEM represents a significant advancement in the automated identification and analysis of particles, such as inclusions and environmental particulate.

The IntelliSEM characterizes large populations of particles accurately, automatically, and rapidly. The IntelliSEM software suite applies high-performance instrument-control and data analysis algorithms to scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS) systems, and provides a rich set of tools for data visualization, mining, and management.

The IntelliSEM Workbench module provides flexibility for data review, particle classification, and reporting. Particle relocation and customized X-ray spectra processing are among the many functions also available in the Workbench.

IntelliSEM Workbench provides tools for reviewing and reporting the acquired data.  The user-friendly interface allows the user to quickly hone in on particles of interest and compile summaries.

Data Management

IntelliSEM uses MSSQL databases to retrieve system parameters and store acquired data, keeping all data in a single location.


IntelliSEM’s Workbench allows multiple users to simultaneously review the data stored in the central database. This allows for a team to work collaboratively and gain new insights.


Multi-resolution imaging allows for analyses to use different magnifications for particle feature detection and measurement. This allows the analysis to search for particles at lower magnifications then increase magnification to measure and acquire elemental information.


Analytical protocols are stored in the database and can be shared among users. The one-button approach further improves reproducibility.


IntelliSEM’s Workbench provides a customizable interface for data visualization and data analysis; user specific visualization tools can be developed to make the review process more efficient.


IntelliSEM’s central database allows for access to the data from multiple locations; users can review and summarize data from the office, remote workplace, or anywhere in the world.

Consulting Services Available

RJ Lee Group’s experts also offer consulting services involving particle analysis utilizing the IntelliSEM technology.
At RJ Lee Group we believe each relationship is unique. Our diverse technology portfolio and in-house experts allow us to support your needs in sample preparation, data acquisition, and data interpretation. We consult with clients in the steel industry, additive manufacturing, environmental, pharmaceuticals and biomedical fields with particle analysis. Let us know how we can help you.
IntelliSEM analysis can be observed during the automated particle analysis process. The SEM field image illustrates the particle size measurement on a PM10 sample with perimeter overlays; and the particle micro-images and X-ray spectra are presented.


Within the IntelliSEM software, the Prospector function collects data and the Workbench allows for data review and reporting.

Prospector is the online analysis module. It takes full control of the SEM/EDS instrumentation and uses intelligent algorithms to rapidly scan large sample areas, while providing fine-grained measurements of each particle detected.


Once Analysis is complete, the Workbench provides a user-friendly interface to allow the analyst to review the results and compile summaries. Summarization protocols can utilize predefined rules, visual review, or clustering algorithms to combine similar features into unique classes. It can also integrate other sample information and characterize results to provide a complete review and report.
