Technical Examples

A method and apparatus for monitoring and controlling the nano-scale flow rate of fluid in the operating flow path of a HPLC system. A first flow sensor is disposed in a first flow path between a first flow-divider and a fluidic tee. A second flow sensor is disposed in a second flow path between a second flow-divider and the fluidic tee. A first recycle flow restrictor is disposed in the first recycle flow path in fluid communication with the first flow-divider. A second recycle flow restrictor is disposed in the second The permeability of each recycle flow restrictor can be selected to produce a desired flow rate with each respective flow path. The output signals of the first and second flow sensors to control output of a pump within each flow path.
