Use clean bottles only.
Exchange water-based solvents daily.
Select solvent volume to be used up within 1 – 2 days.
Use only HPLC-grade solvents and water filtered through 0.2 µm filters.
Label bottles correctly with bottle content, and filling date / expiry date.
Use solvent inlet filters.
Reduce risk of algae growth: use brown bottles for aqueous solvents, avoid
direct sunlight.
Use lower channels (A and/or D) for buffer solutions.
Regularly flush all MCGV channels with water to remove possible salt
deposits.
Check compatibility of buffers and organic solvents to avoid precipitation.
