• Mobile Phase Preparation: Use high-quality solvents and additives for mobile phase preparation, and filter the mobile phase through a 0.2 μm filter to remove particulate matter. Degas the mobile phase to prevent air bubbles from forming in the system.
• Seal Replacement: Replace pump seals regularly to prevent leaks and maintain pressure stability. The frequency of seal replacement depends on the type of mobile phase used and the operating pressure.
• Preventive Maintenance: Schedule regular preventive maintenance with a qualified service engineer to ensure that the system is functioning properly and to identify and address any potential problems before they become serious.

Troubleshooting Tips:

• High Pressure: If the system pressure is too high, check for blockages in the flow path. This could be due to a clogged column, a blocked frit, or a buildup of particulate matter in the system. Flush the system with appropriate solvents to remove any blockages.
• Poor Resolution: If the resolution is poor, check the column condition, mobile phase composition, and system temperature. Replace the column if it is degraded, adjust the mobile phase composition to optimize separation, and ensure that the system temperature is stable.
• Peak Tailing: Peak tailing can be caused by a variety of factors, including column degradation, silanol interactions, and sample overload. Try using a different column, adding a tailing reducer to the mobile phase, or reducing the sample injection volume.
• No Peaks: If no peaks are detected, check the detector settings, sample concentration, and injection volume. Ensure that the detector is properly calibrated and that the sample concentration is within the detector's linear range. Increase the injection volume if necessary.
• Baseline Noise: Excessive baseline noise can be caused by a variety of factors, including contaminated solvents, a noisy detector, or electrical interference. Use high-quality solvents, clean the detector, and ensure that the system is properly grounded.
