What method was used for determining the total and respirable quartz fractions contained within your garnet abrasive products?
We employed an accredited laboratory that used similar analytical techniques that are a part of NIOSH Method 7500. Specifically, these techniques are X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The laboratory has developed a specialized approach that can classify quartz particles based upon respective diameters (microns). This information has allowed us to Read more
