1. A droplet dispensing system for dispensing one or more droplets from a flow of fluid, the droplet dispensing system comprising:
a controller;
a fluid flow channel for receiving at least one flow of fluid;
a first inlet channel coupled to the fluid flow channel for providing a flow of a process fluid to the fluid flow channel;
a suction channel coupled to the fluid flow channel at a first location located downstream from the first inlet channel for ejecting the process fluid;
a vacuum system operatively coupled to the suction channel providing suction for aiding in ejecting the process fluid from the fluid flow channel;
a second inlet channel coupled to the fluid flow channel for selectively providing a pressurized fluid to the fluid flow channel,
wherein the second inlet channel is coupled to a valve controlled by the controller for selectively opening and closing the valve to introduce the pressurized fluid to the fluid flow channel,
a pressurized fluid supply connected to the second inlet channel via the valve for providing the pressurized fluid to the fluid flow channel, wherein, in response to introduction of the pressurized fluid to the fluid flow channel, the fluid flow channel comprises both the process fluid and the pressurized fluid; and
an exit channel coupled to the fluid flow channel at a second location located downstream from the first inlet channel and the second inlet channel for ejecting the process fluid and the pressurized fluid, wherein increased pressure in the fluid flow channel through introduction of the pressurized fluid causes both the process fluid and the pressurized fluid to enter the exit channel from the fluid flow channel and exit the droplet dispensing system via the exit channel.
