TITLE Classification, Separation, and Capture of Ultra- Fine Particles by Impact Separation PRIMARY INVENTORS T.R. Blake and Karl Jakus DESCRIPTION A system for handling, collection and classification of ultra-fine and nano-scale particles is based on impact separation technology through control of the operating environment. The fractional efficiency for particle capture and the cut-diameter are affected by the geometry of the device, flow rate, and operating pressure, together with the particle characteristics. APPLICATIONS Classification of particles and removal of agglomerates. Separation of particles from carrier gas. Collection of powders. ADVANTAGES Based on commercial embodiment with simple design. Ease of scale-up. Continuous operation. Readily integrated with synthesis processes or other collection devices.
