Operating Procedures
Proper operation is crucial for optimal performance. This section details essential procedures, including priming the system, setting flow rates, and managing degasser operation, ensuring accurate and reliable results.
Priming the System
Priming the Waters 2695 Separations Module is a crucial initial step. Begin by filling the solvent bottles with the appropriate mobile phase. Turn on the degasser from the status page to remove dissolved gases. Next, perform a dry prime until solvent flows from each of the four lines, ensuring no air bubbles are present. Once all lines are primed, set the flow rate to 0 mL/min while keeping the degasser on for at least two minutes. This process ensures proper solvent delivery and system stability. Refer to the operator’s manual for detailed instructions and safety precautions.
Setting Flow Rate and Degasser Operation
Proper flow rate and degasser operation are critical for optimal performance of the Waters 2695. First, establish the desired flow rate based on your application needs. The degasser should always be active during operation to remove dissolved gases from the mobile phase, preventing bubble formation and ensuring stable baselines. Monitor the degasser’s performance regularly. Adjust the flow rate gradually to avoid pressure fluctuations and system instability. Ensure the mobile phase is compatible with the system components and degasser. Refer to the manufacturer’s guidelines for recommended flow rate ranges and degasser settings.
