1. A system for regulating flow in a fluidic device, comprising:

  • one or more analytical streams comprising a transport medium and flowing through;

    a pumping system and flow control module;

    a sample introduction module;

    a sample reaction module, the sample reaction module comprising a reaction device in a first analytical stream, the reaction device comprising an analyte produced by a reaction between a sample introduced by the sample introduction module into the first analytical stream and a reagent introduced by the sample reaction module into the first analytical stream;

    a sample detection module, wherein the analyte is detected by a detector comprised in the sample detection module and the analyte has a constant flow at the detector;

    wherein the pumping system and flow control module maintains a constant flow rate of the analyte at the detector by controlling the flow of transport medium in the first analytical stream to compensate for the sample and the reagent introduced into the first analytical stream.
