Si parla della formazione di goccioline in tutto il testo, e alcuni esempi di drop eccoli qui:

Drop delay is the time that elapses between detection of a target at an analytical region to the time at which a sorting condition (e.g. a charging potential) is applied to the droplet. As the droplets are formed they are analyzed to determine whether the drop delay is correct. The droplets are analyzed to determine if the target detected at an analytical region is within the droplet to which the sorting condition is applied.

To generate droplets, a drop drive piston may be used. Signals for the power and operation of the drop drive piston may be sent through transducer electrical terminal. The electronic signal is sent to drop drive piezo element held in transducer plunger. Drop drive piezo element oscillates drop drive piston, sending oscillating pressure waves through the incompressible sheath flow fluid.

In a sorting flow cytometer, the drop drive causes a leading order effect in which the flow stream-in-air, after flowing from the nozzle, breaks into a train of large droplets having a characteristic diameter of the same order of magnitude as the jet diameter

Theoretically, a perfectly symmetric jet excited near its spontaneous drop frequency will break into a droplet chain whose satellite droplets never merge with the parent droplets. A portion of the drop drive energy cascades into a secondary satellite droplet formation harmonic, in phase with the fundamental droplet formation frequency. Some experiments have shown that one method to control the satellite forma-tion is to add a phased, higher-harmonic component to the drop drive vibration or pulsation to alter or cancel satellite development.
