RJ Lee Group provides accurate quantification for bulk total crystalline silica (TCS) for a variety of industries, using a modified version of the NIOSH 7500 method. Clients send samples of rocks or dust from mines, manufacturing facilities, and other sources, and may submit air samples along with the materials for bulk silica analysis. RJ Lee Group’s experts analyze these materials to determine the potential for release of crystalline silica during the mining or manufacturing process.
