Autoclean with multi-wash is not available for dual-needle configurations. |
Mark the Switch Injection Valve check box to specify that the injection valve is switched back and forth to remove any potential sediment from the grooves.
This section is present only when the multi-wash option is installed.
Mark the Execute Multi-wash check box to include a multi-wash step. The Multi-wash table allows you to specify up to three solvents that will be used to clean the system.
For each solvent,
Specify a duration (in seconds) in the Time [s] field.
Mark the check boxes for Seat Back Flush and/or Needle Wash to include these actions. If both are selected, they are carried out simultaneously; if neither is selected, the step is ignored (equivalent to specifying zero duration).
If a needle movement is required, the step can take longer than specified. |
Mark the check box to specify that the main flow path and bypass channels of the sampler are flushed with solvent delivered by the main pump of the system. Specify the flush time (in seconds) for each channel in the adjacent Duration field.
Since the auto-clean procedure flushes both the main flow path and bypass, the total duration of the flow-path flush action is twice the time that you enter. |
