Feed Injection (Online Sample Manager)

This section is available only when Feed injection mode has been selected. The default values depend on the selection in Method Preset.

Feed Speed

    The Feed Speed is the speed of delivery of the sample into the solvent flow.

  • Adaptive

    Select this option to set the Feed Speed to a proportion of the pump flow. Typically, a high value (default 80%) is used for isocratic analyses; and a low value (default 5%) is used for gradient analyses.

  • Fixed

    Select this option to set the Feed Speed to a fixed value; enter the value in the field.

Flush Out

    Specifies the volume of solvent to use to flush out the injection path.

  • Mode

    Mark the automatic check box to use the volume of solvent calculated based on the injection volume and the volumes of the seat and loop capillaries.

  • Volume

    When the automatic check box is cleared, specify the flush-out volume in the field.
