Crystalline Silica Analysis by XRD
Crystalline silica is a naturally occurring mineral found in materials such as sand, soil, granite, and construction products like concrete, glass, ceramics, and engineered stone. When these materials are cut, ground, or drilled, they can release respirable crystalline silica dust—a known health hazard linked to silicosis and other lung diseases.
Why Perform Crystalline Silica Testing?
Testing your product or bulk material is essential to:- Protect worker health and safety
- Comply with OSHA labeling and exposure regulations
- Understand the silica content in your raw materials or finished products
Crystalline Silica Testing by RJ Lee Group
Our XRD lab for crystalline silica in Monroeville, PA offers comprehensive quantitative silica analysis with unmatched sensitivity and accuracy. Our testing includes all three regulated forms of crystalline silica:
- Quartz
- Cristobalite
- Tridymite
Why Choose RJ Lee Group for XRD Silica Testing
- True Bulk Analysis – We analyze 1–2 grams or more of material to ensure results are representative of the entire sample.
- Lowest Detection Limits in the Industry – Our advanced techniques achieve detection limits as low as 0.1% or lower, even in complex mineral matrices which cause interferences in the XRD scans.
- Matrix Reduction for Accuracy – Using specialized heat and acid digestion methods, we reduce the sample matrix prior to analysis to eliminate interferences and enhance sensitivity.
- Expertise with Interfering Minerals – Our sample preparation methods are effective even when crystalline silica is present alongside minerals like mica, clay, feldspar, and barite which cause interferences in the XRD scans.
- Specialized Identification – We also offer a unique XRD method to distinguish between opal and cristobalite, helping you solve complex silica-related challenges.
- Fast turnaround times- We offer a standard 10 working day turnaround time with quicker times available on request. Our lab has 4 Malvern Panalytical XRD instruments on-site, ensuring that instrument repairs will not slow down the receipt of your results.
