Best Practices
How to deal with solvents
• 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 m 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.
Select channels for Multi-Channel Gradient Valve (MCGV)
• 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.
CAUTION
Contaminated seal wash solvent
➔ Do not recycle seal wash solvent to avoid contamination.
➔ Weekly exchange seal wash solvent.
