4. Locate the source of the leak.
As leakage usually occurs at a connection, visually inspect all
components and connections in the flow path.
The following can help you to identify the source:
Nebulizer
If liquid is visible on the nebulizer, leakage may have occurred in the
nebulizer. Remove the nebulizer from the detector (see
section 7.7,
page 179 ). Inspect the nebulizer for signs of leakage.
♦
If no signs for leakage are present, re-install the nebulizer (see
section 5.5.3, page 77 ).
♦ If signs of leakage are present, proceed with the steps below.
Corona Veo RS only: Stream-switching valve
If liquid is visible on the stream-switching valve, leakage may have
occurred on the capillary connections on one of the ports. Inspect
the capillaries for signs of leakage.
5. Tighten or replace the connection or component as required.
6. 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.
7. Allow the sensor to adjust to the ambient temperature for a few
minutes.
8. Turn on the detector with its main power switch.
9. If you operated the detector from the chromatography data system,
reconnect the detector from the software.
10. If leakage is no longer reported, you can resume operation.
