摘要:
Described are microparticle fractionating apparatus and methods of fractionating microparticles. Multiple electrodes may be used to charge droplets when separating and collecting microparticles based on a result analyzed by an optical methodologies. A first electrode may be used to charge a sample fluid, and a second electrode used to apply additional charge near a droplet break-off point.

There is provided a microparticle sorting device that automatically optimizes a fluid stream. There is provided a microparticle sorting device that includes a voltage supply unit that supplies a driving voltage to a vibratory element that applies vibration to an orifice that produces a fluid stream, a charge unit that imparts charge to at least some droplets ejected from the orifice, deflecting plates, arranged opposing each other with the fluid stream S therebetween, that vary a travel direction of the droplets, and a first image sensor that acquires an image of the droplets passing between the deflecting plates. The microparticle sorting device is equipped with a controller that detects the droplets in the image, sets a standard band corresponding to a width of the droplets before imparting the charge, and controls the driving voltage of the voltage supply unit so as to further decrease a quantity of the droplets detected in areas within a designated number of pixels from the standard band from among the droplets after imparting the charge.

A separation arrangement is provided for separating between particles of different materials having different densities and comprised in a mixture of fine particles. The arrangement comprises: a solid particles feed ingress means, a solid particles pushing/pulling means and at least one mesh adapted to stop particles of the lighter material. The particles comprised in the mixture are allowed to free fall within the separation arrangement, and particles of the lighter material are being extracted away from the free falling particles by the solid particles pushing/pulling means and conveyed towards the at least one mesh. The particles of the heavier material are allowed to complete their free fall and to reach the lower part of the separation arrangement.
