Note the following:

  • The dual pump combines two ternary pumps in a single enclosure.

  • The two pumps are referred to as left pump and right pump.

    • On the keypad, L refers to the left pump and R refers to the right pump.

    • In the Chromeleon user interface, Left refers to the left pump and Right refers to the right pump, for example, as in PumpLeft_Pressure and PumpRight_Pressure.

  • The dual pump can be shared by two different instruments (see Sharing the Dual Pump).

  • You can monitor the solvent consumption of the dual pump as a whole or separately for each pump (see Monitoring the Solvent Consumption).

  • You can monitor the liquid level in the waste container of the dual pump as a whole or separately for each pump (see Monitoring the Liquid Level in the Waste Container).
