The spectrometer is fitted with PTFE gas supply hose assemblies,
1.8 meters (6 feet) in length fitted with Swagelok hardware. Gas
supply adapters are included with each instrument to connect the
instrument to regulated gas supplies.
The user (or other authorized personnel) must carry out appropriate
leak tests necessary to ensure safety on the gas and liquid
connections that the operator is directed to assemble during
installation, normal use or maintenance.
Storage Cylinder Instructions
Cylinders containing gas under pressure should be firmly secured to
a rigid structure, and the storage area must be adequately ventilated.
Never locate gas cylinders near a source of ignition, or in a position
that is subject to direct heat. Gas storage cylinders often incorporate
a pressure release device, which will discharge the gas at a
predetermined temperature, usually around 52 °C (125 °F).
If gases are to be plumbed from a remote storage area to the
instrument site, ensure that the local outlets are fitted with stop
valves, pressure gauges and suitable regulators, which are easily
accessible to the instrument operator. The gas outlets must be
provided within 1.5 meters (5 feet) of the instrument.
