MICROPARTICLE SORTING DEVICE AND METHOD OF OPTIMIZING FLUID STREAM THEREIN |
摘要 |
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. |

1. A microparticle sorting device comprising:
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 therebetween, that vary a travel direction of the droplets; a first image sensor that acquires an image of the droplets passing between the deflecting plates; and 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. |
