What to do if no system is found when starting up UNICORN on GE AKTAprocess?
If no system is found when starting up UNICORN, ensure the system is switched on. Check the communication cable and connectors. Reboot the PC: shut down Windows, switch off the SYSTEM POWER SWITCH, wait at least 5 seconds, and then restart the system.
What to do if there is a power failure during a run with GE Laboratory Equipment?
If there is a power failure during a run, check the circuit breaker, both in the system and for the external supply, as applicable.
What to do if I see a ghost peak in GE AKTAprocess?
A ghost peak usually indicates dirt or residues in the flow path from previous runs. Clean the system to resolve this issue.
What to do if the alarm 'Valve error' is displayed on GE AKTAprocess?
If the 'Valve error' alarm is displayed, perform a valve calibration. If the calibration doesn't restore the valve function, contact your local GE Healthcare representative. Note that if the 'Valve error' alarm is accompanied by 'No air supply to the system', the alarm is caused by a compressed air failure.
What to do if there is erratic flow, noisy baseline signal, or irregular pressure trace in GE Laboratory Equipment?
Erratic flow, a noisy baseline signal, or an irregular pressure trace can be caused by gas bubbles passing through or trapped in the pump. Ensure there is a sufficient supply of liquid and check all connections for leaks.
What to do if there is little or no flow in GE Laboratory Equipment?
If you experience little or no flow, check that the connected inlet is actually in use. Ensure inlet containers are not placed too low relative to the pump. Verify that there is liquid supplied to the pump. Also, check the tubing from the inlet container for issues like excessive length, small internal diameter, narrow sections, or blockages. A malfunctioning valve at the container battery limit could also be the cause.
How to resolve a dirty conductivity cell issue in GE Laboratory Equipment?
To resolve a dirty conductivity cell issue, clean the conductivity cell, refer to Clean the UV and conductivity cell.
What to do if temperature compensation is not properly set in GE AKTAprocess Laboratory Equipment?
If the temperature compensation is not properly set, check the temperature compensation settings.
How to resolve residues in the column from previous runs in GE AKTAprocess Laboratory Equipment?
To resolve residues in the column from previous runs, clean the column according to the column instructions.
What to do if the actual flow rate deviates from the displayed flow rate on GE AKTAprocess Laboratory Equipment?
If the actual flow rate deviates from the displayed flow rate, or a flow rate is displayed when the pumps are off, this can be caused by changes in running conditions. Perform a zero-point adjustment of the flow meter to resolve this.
