IntelliSEM Particle Analysis

Seeing It All: Automating the Scanning Electron Microscope

RJ Lee Group’s IntelliSEM particle characterization system represents a significant advancement in the automated identification and analysis of inclusions, particles, and fibers. The IntelliSEM system has been developed upon the Tescan SEM platform with silicon drift EDS detector (SDD) technology. The advanced Tescan optics and integrated SDD allow the IntelliSEM on-line analysis software (Prospector) to characterize features in fractions of a second.

Combining a scanning electron microscope (SEM), x-ray analyzer (EDS) and intelligent software to create CCSEM (computer-controlled scanning electron microscopy), IntelliSEM efficiently locates, sizes, and characterizes large numbers of individual particles. The patented Personal SEM (PSEMTM)1 first-generation integrated SEM/EDX system and the ASCAT – Automated Steel Cleanliness Analysis Tool for comprehensive inclusion analysis as part of process monitoring for steel production.

How It Works

Once the analysis is complete, the IntelliSEM Workbench provides a powerful, user-friendly interface to allow the analyst to review the results and compile summaries in an efficient manner. Summarization protocols can utilize predefined rules, visual review, or clustering algorithms to combine similar features into unique classes. Customizable tables and charts allow for both standard and unique ways to view results for interpretation.

The Workbench can also integrate other sample information and characterize results to provide a complete review and report. The interface can be tailored to the clients’ needs with specific data views and reports. Those views can then be saved and used at a later date for rapid summarization of data.

Data storage uses a SQL database and can be accessed remotely via VPN. Analyses can also be stored to the cloud or transferred to local computers for data portability.
