Follow the steps depending on the location of the leak:
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.
Drain outlet of the flow cell (see figure),
or connection from flow cell to
connection unit 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, 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.
4. Allow the sensor to adjust to the ambient temperature for a few
minutes.
5. If leakage is no longer reported, you can resume operation.
