After using buffer solution as the mobile phase, replace the solvent in the
reservoir bottle with water.
After using buffer solution as the mobile phase, do NOT replace with an
organic solvent such as 2-propanol without first replacing with water.
When using a buffer solution in the reservoir bottle, replace with distilled
water or purified water, and after pumping at least 20 mL into the instrument,
replace with new 2-propanol. If the buffer solution is directly replaced with
2-propanol, crystals will be precipitated, which can cause damage to the
plunger seal or cause problems with the check valve.
