[Object] To provide a micro-particle sorting apparatus capable of performing a high-speed analysis and a safe, high-speed, inexpensive sorting by eliminating cross contamination between samples, contamination of a sample, biohazard with respect to users, and a flow cell and an orifice part, which are expensive, a fine adjustment work of the flow cell and the orifice. [Solving Means] Provided is a micro-particle sorting apparatus A including: a microchip 1 in which a flow path 11 through which liquid containing a micro particle flows and an orifice 12 through which the liquid flowing through the flow path 11 is discharged into a space outside the chip are provided; an oscillating element 2 for transforming the liquid into a liquid drop and discharging the liquid drop at the orifice 12; a charge means for adding an electric charge to the discharged liquid drop D; an optical detection means 3 that detects an optical property of the micro particle flowing through the flow path 11, upstream of a liquid-delivering direction with respect to the orifice; paired electrodes 4, 4 provided so as to be opposed to each other while sandwiching the moving liquid drop D therebetween along a movement direction of the liquid drop discharged into the space outside the chip; and two or more containers that collect the liquid drop passing between the paired electrodes 4, 4. |
