Ozone Generation Problems
Before troubleshooting the ozone generator, first verify that the
other components of the system operate normally. For example,
check for leaks in the detector external connections, check for
leaks in the inlet and inlet column fitting, check that the
vacuum pump operates normally, check that the inlet and ALS
are operating normally, and so on.
Troubleshoot ozone generation as follows:
1
On the GC display, note the detector output signal.
2
Leave the vacuum pump on and ozone supply gas flowing.
3
Turn off the ozone generator.
4
Observe the detector output signal.
5
Turn on the ozone generator and check the detector output
signal again.
A properly operating detector will typically display a difference
in background signal between ozone supply gas voltage on and
off. If no change is observed, contact Agilent service.
