Assignee: ALLIED FLOW INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A particle sorting apparatus comprising:
a flow cell including a flow channel;
an imaging element that obtains an image regarding a flow axis of the flow channel;
a light intensity detector that detects an intensity of light emitted from a light emitting object included in a liquid flowing in the flow channel;
a moving mechanism that moves the flow cell; and
a controller that controls the moving mechanism, wherein
the controller performs a coarse adjustment onto a position of the flow cell based on the image while controlling the moving mechanism to continuously move the flow cell at a first speed,
the controller performs a final adjustment onto the position of the flow cell to allow a first intensity of first light emitted from the light emitting object to be maximum, while controlling the moving mechanism to move the flow cell at a second speed that is lower than the first speed, the first intensity of the first light being detected by the light intensity detector and,
the controller performs a fine adjustment onto the position of the flow cell to allow a second intensity of second light emitted from the light emitting object to be maximum, while controlling the moving mechanism to continuously move the flow cell at a third speed that is lower than the first speed and that is higher than the second speed, the second intensity of the second light being detected by the light intensity detector.
