Troubleshooting
Leaks
Ozone leaks
If you suspect an ozone leak, shut down the detector. Do not
open the detector mainframe. Contact Agilent for service.
Hydrogen leaks
Check all external connections for leaks. See
on page 99. Check the supply
connections to the detector mainframe and between the
detector mainframe and the burner assembly. If you suspect a
leak inside the detector mainframe, contact Agilent for service.
Do not open the detector mainframe.
Oxidizer leaks
Check the oxidizer supply connections to the detector
mainframe and between the detector mainframe and the burner
assembly. See
“Checking for hydrogen and oxidizer leaks”
WARNING
Ozone is a hazardous gas and a strong oxidant. Exposure to ozone
should be minimized by using the instrument in a well-ventilated
area and by venting the exhaust of the vacuum pump to a fume
hood. The ozone generator should be turned off when the
instrument is not in use.
WARNING
Do not measure hydrogen together with air or oxygen. This can
create explosive mixtures that may be ignited by the high burner
temperature. To avoid this hazard: 1. Cool the burner before you
begin. 2. Always measure gases separately.
WARNING
Oxygen rich environments can promote combustion and even
result in spontaneous combustion under conditions of high
pressure and exposure to contamination. Use only oxygen rated
components and ensure that components are oxygen clean prior
to use with pure oxygen.
