Abstract
Disclosed are a system and method for regulating flow in an exemplary fluidic device comprising a fluidic stream carrying a transport medium, sample and one or more reagents for analysis and synthesis of reaction products. The flow rate of the fluidic stream is maintained constant by adjusting the flow rate of transport medium to compensate for the introduction of sample and reagents. An embodiment controls the flow rate of transport medium using a pump, a back pressure regulator, and a variable-sized orifice. Single and multiple channel embodiments are disclosed.
