RJ Lee Group provides accurate quantification of bulk total crystalline silica (TCS) and respirable crystalline silica (RCS) for a variety of industries, using a modified version of the NIOSH 7500 method.

Bulk Silica Analysis


Clients send samples of rocks or dust from mines, manufacturing facilities, and other sources. Often, clients that routinely test air samples will send a portion of the bulk material that is being used in their industry to determine the potential for release of crystalline silica into the air while working with that material.
