Abstract:
1. A particle collector for collecting particles of a discrete particle mass/size separated from a flow of an ambient fluid medium, the collector comprising a chamber having mounted therein a substrate which is rotatable about an axis and onto which separated particles can be directed, the substrate having thereon a plurality of circumferentially-spaced channels each extending in a direction away from said axis and leading to a plurality of chambers in which the particles can be collected while the substrate is rotating, the collector further comprising means for depositing a fluid onto the substrate to form a film of said fluid at least in a region of the substrate onto which particles are directed during operation of the collector, the construction and arrangement of the collector being such that, as particles are deposited in the fluid, the fluid is caused to bear said particles to flow into the plurality of channels for deposition of the particles in the plurality of chambers.
