WebHydrodynamic focusing resolves these problems. In hydrodynamic focusing, a steady flow of diluent is drawn through the aperture, and the cell suspension is injected into this moving body of liquid in a fine stream close to the aperture entrance (Fig. 27-3). The likelihood of two cells passing through the aperture together is dramatically ... WebAbstract. An ultra-fine liquid atomization procedure combining the advantages of electrospray and flow focusing is presented. Both techniques are known to produce strikingly small and steady liquid micro-jets issuing from menisci held by capillary forces. Such menisci take the form of a cusp-like drop attached to the feeding tube (flow …
