The Agilent ICP-OES is supplied with three PVDF gas supply hose
assemblies, each 3 m (9.8 ft) in length fitted with 1/4 inch Swagelok nut
and ferrule set.
Fittings for the regulator end must be supplied by the customer.
Alternatively, a fittings kit can be ordered from Agilent Technologies.
See the Agilent website at www.agilent.com for ordering information.
Customers will provide connection from the gas supply to a shutoff
valve.
Customers must provide pressure regulators for the gas cylinders.
When ordering, consider the size of the output tubing, 1/4 inch
(6.4mm), and also the Compressed Gas Association (CGA) number.
If the Nitrogen Purge option is purchased, additional fittings will be
supplied to connect the gas to the ICP-OES.
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).
