1. method comprises:

  • By transfer pipeline fluid is communicated to chromatographic column;

    Determine the inlet pressure of the inlet end of transfer pipeline;

    Determine the top hole pressure of the endpiece of transfer pipeline;

    WithThe pressure of regulating the inlet end of transfer pipeline based on determined entrance and exit pressure produces the flow velocity of expecting with the endpiece at transfer pipeline.
