Droplet separation device, separation signal generation device, separation signal generation method, and program

A separation signal generation device comprising:

• a memory;
• and
• a central processing unit connected to the memory and that:
• generates a first trigger signal at a time when a separation target is detected, the separation target being wrapped in a droplet and flowing through a microchannel together with a first fluid;
• generates a second trigger signal at a time when the droplet flowing through the microchannel passes through a predetermined position in a flow velocity direction of the microchannel;
• determines whether or not a determination signal which is a sum of a magnitude of the first trigger signal and a magnitude of the second trigger signal is equal to or more than a predetermined threshold value;
• and
• outputs a separation signal for separating the separation target in a case where the determination signal is equal to or more than the threshold value.

A non-transitory computer readable medium storing a program causing a computer to execute:

• generating a first trigger signal at a time when a separation target is detected, the separation target being wrapped in a droplet and flowing through a microchannel together with a first fluid;
• generating a second trigger signal at a time when the droplet flowing through the microchannel passes through a predetermined position in a flow velocity direction of the microchannel;
• determining whether or not a determination signal which is a sum of a magnitude of the first trigger signal and a magnitude of the second trigger signal is equal to or more than a predetermined threshold value;
• and
• outputting a separation signal for separating the separation target in a case where the determination signal is equal to or more than the threshold value.
