Description of ease of detection of analytes in respirable dust samples: LOD and LOQ for silica were 10 and 30 ug/sample while LOD and LOQ for respirable dust were 30 ug/sample and 87 ug/sample. The analytical range for respirable crystalline silica was 10 to 200 ug/sample. The analytical range for respirable dust was 30 to 200 mg.
