Abstract
Systems and methods for metering microfluidic volumes are provided. A discrete plug may be separated from a larger volume of first fluid by injecting a second fluid, such as a gas, into a channel containing the first fluid. The injection of the second fluid to isolate the desired amount of the first fluid may be controlled through timing of flows, visual indicators and/or automated control systems using optical or electrical sensors.
