What to do if pump is not working in GE AKTAprocess?
If the pump is not working, check if the emergency button has been pressed. Also, verify the air supply pressure and adjust it if needed. Inspect the method and valves. Try entering Pump:ManFlow > 1%. If the issue persists, contact GE Healthcare service personnel.
How to fix noisy UV-signal, signal drift or instability in GE AKTAprocess?
Noisy UV-signal, signal drift, or instability can be caused by bad UV fiber connections. Check the connections of the UV cell optical fiber and replace them if necessary.
How to fix compressed air failure during a run in GE Laboratory Equipment?
If there is a compressed air failure during a run, it may be caused by insufficient air pressure due to malfunctioning air supply equipment or a leaking air hose. Rectify the air supply problem and restart the run by pressing the Continue button.
What to do if there is too high outlet pressure in GE AKTAprocess Laboratory Equipment?
If there's too high outlet pressure, verify that the connected outlet is actually in use and that outlet containers are not placed too high relative to the pump. Inspect the tubing to the outlet container for excessive length, small internal diameter, narrow sections, or blockages. Also, check for any non-functioning valves or a malfunctioning valve at the container battery limit.
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.
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 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 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 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.
