This section is present only when no multi-wash option is installed.
Wash Right Needle |
Mark the check box to specify that the right needle is washed. Specify the wash time (in seconds) in the adjacent Duration field. |
Wash Left Needle (Dual-needle configurations only) |
Mark the check box to specify that the left needle is washed. The wash time is the same as for the right needle. |
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. |
