Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus for directing particles entrained in a fluid. SOLUTION: This apparatus for directing particles entrained in the fluid comprises a chamber having a first wall, including means for generating a sound wave having a frequency ν, and a second, opposite wall capable of reflecting the sound wave. The first and second walls define a conduit for the passage of the fluid, and the thickness of the second wall is such that the path length of the standing wave in the second wall is a multiple of about 1/2 the wavelength λrof the sound wave therein.
