Compressed Gases

WARNING WARNING
Avoid banging the valves and ensure that the correct valves and gauges are installed.
Gas cylinders should be stored (and placed) outside the laboratory and connected to
the instrument through specially cleaned copper tubing. Use care to prevent kinking
or stressing the gas tubing. For safety, cylinders should be firmly clamped in an
upright position.
WARNING WARNING
Ensure that all hydrogen line couplings are leak-free and do not allow hydrogen to
vent within the oven.

Ventilation

WARNING WARNING
In addition, adequate ventilation must be provided, particularly if a liquid nitrogen
or carbon dioxide sub-ambient accessory is in constant use. The area underneath the
bench (around the fore pump) should be well ventilated . An oil separation filter and
charcoal trap should be installed at the outlet of the fore pump exhaust to prevent
contamination if fume hood venting is unavailable.

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 either in the GC oven or the Clarus SQ 8
vacuum manifold.
Hazardous vapors . When analyzing hazardous compounds, such Hazardous vapors
as pesticides, it is necessary to arrange for venting of the mass
spectrometer effluent from the fore pump exhaust into a fume
hood or charcoal trap.
