Enabling Halt on Bad Compression Check
To stop the next injection if the mobile phase fails the compression check:
1. Ensure that the compression check is enabled (Section 4.5.3,
Performing a
Compression Check).
2. Use the arrow keys to select Yes for Halt on Bad Compression Check (Figure 4-29
).
4.8.5 Using Buffered Mobile Phase
When using buffered mobile phases:
• Do not make abrupt changes from buffered aqueous solutions to organic solvents.
• Do not let the buffered mobile phase sit in the system. Always maintain a minimal
flow.
• Enable the purge in idle mode during unattended operation.
• Remove the mobile phase before powering down (see Section 3.8,
Power Down and
Storage).
Note: Program the pump for a minimal flow after the last run to prevent damage to LC
components.
