 through the air sampler. A liquid level control may be provided for the reservoir.
Thus, the cyclonic cup, the stripping column and the demister may be xe2x80x9cself-pumpingxe2x80x9d, in the sense that no external liquid pump may be needed to force the stripping liquid through them, since that job may be done by the action of the air/liquid shear forces generated by the upwardly rising air vortex within them; and since no external liquid pump may be needed to recirculate the stripping liquid from the demister""s reservoir back into the cyclonic cup, since that job may be done by gravity feed.
All along its journey from the cyclonic cup""s input port to the demister""s reservoir, the thin film of stripping liquid may strip the target material from the upwardly rising air vortex at high efficiencies. Such high efficiencies may be due to such factors as the high velocity of the circulating air and the upwardly rising air vortex; the very large surface area of the thin film; the very long path followed by the thin film as it flows across the cyclonic cup""s base and spirals up the inside of the inner surfaces of the sidewalls of the cyclonic cup and the stripping column; the very low volume of stripping liquid that resides in the air sampler""s main body and air inlet section at any one time; the very low flow rate of the stripping liquid through the air sampler""s main body and air inlet section; the very high volume of air flowing through the air sampler; and/or the evaporation of substantial amounts of the stripping liquid by the air flowing through the air sampler.
The internal diameter of the stripping column may be less than that of the cyclonic cup, to cause the air vortex within the stripping column to rotate at a higher speed as compared to the air vortex in the cyclonic cup. The higher speed of rotation may help the stripping column to more effectively strip liquid and solid particulate target material from the air due to higher centrifugal forces; and may create a relatively lower pressure within the stripping column that may permit the relatively higher pressure within the cyclonic cup to urge the stripping liquid from the inner surface of the cyclonic cup to the inner surface of the stripping column.
The inner surface of the stripping column may be provided with spiral grooves for increasing its surface area; for providing a long spiral path for the thin film of stripping liquid to follow on its inner surface; and/or
through the air sampler. A liquid level restraint may be provide for the reservoir. 
 Thus, the cyclonic cup, the stripping column and the demister may be xe2x80x9cself - pumpingxe2x80x9d, in the sense that no external liquid heart may be needed to force the stripping liquid through them, since that occupation may be done by the action of the breeze / liquid shear forces beget by the upwardly rising atmosphere whirl within them; and since no external liquid pump may be needed to recirculate the stripping liquid from the demister""s reservoir back into the cyclonic cup, since that job may be done by graveness feed. 
 All along its journey from the cyclonic cup""s input port to the demister""s reservoir, the sparse film of stripping liquid may plunder the target fabric from the upwardly rise air vortex at high efficiency. Such high efficiencies may be due to such factors as the high velocity of the circulating air and the upwardly rising air vortex; the very large surface area of the thin film; the very retentive path followed by the flimsy film as it flows across the cyclonic cup""s base and spirals up the inside of the inside surfaces of the sidewall of the cyclonic cup and the stripping column; the very low bulk of stripping liquid that resides in the air sampler""s main body and air inlet department at any one time; the very low flow rate of the strip liquid through the breeze sampler""s main body and air inlet section; the very high volume of tune flowing through the air sampler; and/or the vaporization of substantial amounts of the stripping liquid by the air flow through the air taster. 
 The internal diameter of the stripping column may be less than that of the cyclonic cup, to induce the air vortex within the stripping column to rotate at a high speed as compare to the air vortex in the cyclonic cup. The higher speed of rotation may help the denudation column to more effectively strip liquid and firm particulate target material from the air due to higher centrifugal forces; and may make a relatively lower pressure within the denudation column that may permit the relatively higher pressure within the cyclonic cup to urge the stripping liquid from the inner surface of the cyclonic cup to the inside surface of the stripping column. 
 The inner surface of the stripping column may be provided with spiral grooves for increase its open area; for providing a long spiral path for the thin movie of stripping liquid to follow on its inner surface; and/or
