8.3 Operating Issues
This section gives an overview of possible operating issues and remedial
actions.
8.3.1 Resolving Liquid Leaks
When
The leak sensor is wet. The leak sensor reports leakage.
Parts and additional items required
• Replacement part as required
• Cloth or tissue
Preparations
When resolving leakage, observe the safety guidelines and general rules
for maintenance and service as presented in

Follow these steps
1. Locate the source of the leak. Leakage usually occurs at a
connection. However, leakage may also have occurred inside the
flow cell.
Location of the leak Steps
Flow cell inlet and/or outlet 1. Tighten the connection where liquid is
visible.
2. If the connection seems tight but is still
leaking, remove the connection/fitting
and check for damage.
3. If necessary, replace the inlet capillary
or waste line.
Leak tray but not flow cell inlet or outlet 1. Remove the flow cell from the detector
and inspect the flow cell for signs of
leakage.
2. If signs of leakage are present at the
flow cell, carefully dry the flow cell
opening in the detector and let
remaining moisture evaporate before
you replace the flow cell.
3. With a cloth or tissue, thoroughly absorb all liquid that has collected
in the leak tray and under the leak sensor. Be careful not to bend the
sensor.
