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 Maintenance and Service.
Follow these steps
Locate the source of the leak. Leakage usually occurs at a connection. However, leakage may also have occurred inside the flow cell. In this case, leakage may occur at the drain outlet of the flow cell (see figure).
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. |
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.
Allow the sensor to adjust to the ambient temperature for a few minutes.
If leakage is no longer reported, you can resume operation.
