Abstract
A virtual cyclone sampler of a hollow rectangular container is provided with an arcuate surface by chamfering an edge thereof. The virtual cyclone sampler is further provided with two guide slots which are located at junctions of the arcuate surface and two adjacent planes sharing the chamfered edge. The guide slots are intended to guide gas or airborne particles to flow into or out of the container. Two virtual cyclone samplers may be connected in symmetry to form a composite virtual cyclone sampler.
