6)  Wait until a steady stream of solvent comes out of the purge valve waste tube. 
7)  Repeat steps 3 through 6 for the other channels of the pump. Change to the 
composition for your next run, %B=70. 
8)  Turn off the pump. 
9)  Close the purge valve. Set the required composition and flow rate for your 
next application. In this case: Flow 1.5 mL/min and %B 70. 
10) Turn on the pump and allow the column to equilibrate. 
Note: Always keep HPLC grade solvent in all pump channels to prevent valve 
damage even when the channel is not being used. For a reversed phase system, 
place water with 20% methanol in the unused channels.
