Object Research Systems (ORS), Montreal, Canada, is now offering CT Powder Analysis through its Product Testing Services. Using its proprietary software and 3D X-ray imaging, the company provides clients with full volumetric data and analysis of metal powders for R&D and quality assurance purposes.
According to ORS, laser diffraction and other conventional powder testing methods do not provide the same depth of analysis as CT scanning, which can reveal powder characteristics only visible through X-ray. After scanning, a 3D visualisation of the powder can be produced, with the option to add visual details and animation for presentations.
By visualising powder structure in 3D, ORS states that it enables its clients to extract meaningful quantitative descriptions relating to size and spatial distribution, as well as accurate data on sphericity, particle aspect ratio, size and porosity.
The company also offers a Complete Scanning Schedule Plan Analysis, which can be used to determine the variability of powders from, for example, nominally identical batches. This is expected to enable companies to provide better quality control.
