Safe Handling of Gases
When using hydrogen, either as the combustion gas for a flame ionization detector or as a
carrier gas, special care must be taken to avoid buildup of explosive hydrogen/air mixtures.
Ensure that all hydrogen line couplings are leak-free and do not allow hydrogen to vent
within the oven.
Ventilation
Adequate ventilation must be provided, particularly if a liquid nitrogen or carbon dioxide
subambient accessory is in constant use. When analyzing hazardous compounds, such as
pesticides, it may be necessary to arrange for venting of detector effluent into a fume hood.
Using Hydrogen
WARNING
Flame Ionization Detectors (FID) and Flame Photometric Detectors
(FPD) use hydrogen as fuel. If the hydrogen is turned on without a
column attached to the injector and detector fittings inside the oven,
hydrogen could diffuse into the oven creating the possibility of an
explosion. To avoid possible injury, DO NOT TURN ON THE
HYDROGEN UNLESS A COLUMN IS ATTACHED AND ALL
JOINTS HAVE BEEN LEAK TESTED.
Before disconnecting a column, make certain that the hydrogen has
been turned OFF.
If two FIDs or FPDs are installed and only one has a column attached
to it, make certain that you cap off the unused detector inlet fitting with
a 1/8-inch stainless steel plug (P/N N930-0061).
WARNING
Contact the gas supplier for a material safety data sheet (MSDS)
containing detailed information on the potential hazards associated
with the gas. Carefully use, store, and handle compressed gases in
cylinders. Gas cylinders can be hazardous if they are mishandled.
