Figure 1
In vitro dry particulate testing revealed the particulates that were visible using PCXI. Samples were examined under PCXI (main pictures) and light microscope (insets): (a) asbestos, (b) quarry dust, (c) fibreglass, (d) galena and (e) silver-coated hollow glass beads. The morphology of each of the particulates is clearly very different. For layout and presentation purposes, and so they are at the same level of magnification, the PCXI images are cropped to 0.90 mm × 0.60 mm, and the light microscope images are 0.365 mm × 0.27 mm.
