Abstract

The present application discloses a system and a method for calculating a droplet delay time in a liquid flow of a sorting device. The system includes: a first laser source configured to emit a first laser beam to a liquid flow of a sorting device, the first laser beam and the liquid flow intersecting at a first laser interrogation point; a second laser source configured to emit a second laser beam to the liquid flow, the second laser beam and the liquid flow intersecting at a second laser interrogation point; and a droplet delay time calculation unit configured to calculate, based on of the time when the particle in the liquid flow passes through the first and second laser interrogation point and the time when the particle passes through the second laser interrogation point, a first delay time, and calculate, a droplet delay time.
