Compressed Gases
Compressed Gases. High pressure gas cylinders can be dangerous if
mishandled or misused. Always handle gas cylinders with caution and
observe your local regulations for the safe handling of gas cylinders.
WARNING
Avoid banging the valves, and ensure that the correct valves and gauges are
installed. It is recommended that gas cylinders be stored and placed outside the
laboratory and connected to the instrument through specially cleaned copper tubing.
Take care not to kink or stress the gas tubing. For safety, cylinders must be firmly
clamped in an upright position.
Explosive hazard. When using hydrogen, methane or isobutane, special
care must be taken to avoid buildup of explosive gas mixtures either in the
GC oven or the mass spectrometer vacuum manifold.
WARNING
Ensure that all hydrogen line couplings are leak-free and do not allow hydrogen to
vent within the oven.
Ventilation
WARNING

Hazardous vapors. When analyzing hazardous compounds, such as
pesticides, or running in the chemical ionization (CI) mode, it is
necessary to vent the mass spectrometer effluent from the forepump
exhaust into a fume hood or charcoal trap.
