5) When the air in the piping tube has been replaced with nitrogen, click [OFF] to stop the purge operation. (If the piping tube provided is used, this takes approximately 30 to 40 s.)
3. Mounting the Reagent Bottles
NOTE: Allow the reagent bottles to reach room temperature before opening them.
4. Preparation for Column Attachment
Before attaching the column, replace the contents of the piping with mobile phase.
1) Clean the pump unit's suction filter(1) with a small amount of new mobile phase.
Next, put the suction filter in a bottle(2) of mobile phase.
2) Open the pump unit's drain valve by turning the lever(3) 180º counterclockwise.
