Capabilities
Respirable Crystalline Silica Testing
As a leading provider of X-ray Diffraction (XRD) analysis, RJ Lee Group specializes in the precise phase identification and quantification of quartz, cristobalite, and tridymite. We provide important data for air quality monitoring, including special testing for respirable crystalline silica (RCS). Our laboratory supports compliance with OSHA, MSHA, and NIOSH regulations, utilizing state-of-the-art instrumentation to deliver low detection limits and rapid turnaround times.
Inhaled silica dust is a significant health hazard for those in mining, construction, and manufacturing; over time, accumulation can lead to silicosis, COPD, and other respiratory issues. Because silica becomes respirable during common industrial activities—such as grinding concrete, mixing cement, or drilling rock—regulatory bodies have established strict Permissible Exposure Limits (PEL). We partner with mine operators, construction firms, and EH&S consultants to monitor worker exposure, validate Safety Data Sheets (SDS), and support environmental remediation or litigation efforts through expert data interpretation and sampling guidance.

Identifying interferences
RJ Lee Group's state-of-the-art technology allows us to detect silica at very low levels and from short exposures. Our experts leverage this increased sensitivity, coupled with years of experience, to identify iterferences in collected samples. Other minerals, such as mica, clays, kaolin, feldspar, and graphite can greatly reduce the accuracy of test results if they are not properly classified. Identifying these interferences can also alert you to other issues you may not have been aware of.
