Recommended Interval for Preventive Maintenance
The recommended interval for preventive maintenance is:
• 100 L (150 L for Long Life Technology) or 1 year (whichever comes first).
This recommendation is valid for LC instruments on which “typical” applications
are running.
A “typical” application can be characterized as follows:
• pressure range 100 – 800 bar,
• flow rates 0.5 – 3.5 mL/min,
• typical solvents used in reversed phase LC.
