DP/SP Shutdown
If the ICS-3000 Dual Pump (DP) or ICS-3000 Single Pump (SP) will not be
operated for a period of one week or more, follow the instructions below:
• Fill the pump with methanol (or a similar alcohol, such as 2-propanol or
ethanol). If the eluents in the pump are not miscible with water, replace the
eluents step-by-step.
• Fill the seal wash reservoir with wash solution (see Section 2.2.5).
• Rinse out buffers. This will reduce the time required for column equilibration
when you resume operation.
• Disconnect the tubing from the peristaltic pump on the component panel: lift
the lever up and to the right, remove the tubing, and release the lever (see
Figure 6-1
).
