Quantitative XRD, respirable silica dust analysis

X’Pert³ Powder and CubiX³ diffraction systems equipped with the X’Celerator detector offer excellent low limits of detection for silica phases – down to 3 μg – and a significantly shorter measurement time compared to traditional point detectors.

Airborne silica particles pose a carcinogenic threat at concentrations as low as 50 μg/m3. Standard methods such as NIOSH7500, OSHA ID-142, and MDHS 51/2 use XRD to quantify the mass of SiO2 phases per volume of air sampled directly on the polymer collection filter or on samples ashed and deposited on silver membranes.
