Abstract
A cyclone includes a hollow cylindrical upper portion and a hollow conical lower portion having an inclined wall and a base wall. The base wall and the inclined wall are continuous contact with each other, and the inclined wall of the hollow conical lower portion is in continuous contact with an outer wall of the hollow cylindrical upper portion. A total cyclone height is from about 10 to about 30 millimeters, and a ratio of the total cyclone height to an inner diameter of the hollow cylindrical upper portion is from about 0.7 to about 1.3. An angle between an inner surface of the base wall and an inner surface of the inclined wall is from about 110 to about 130 degrees.
