44 Agilent 5100 and 5110 ICP-OES Site Preparation Guide
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.
Cryogenic Liquids
Cryogenic liquid gases are stored under pressure at very low
temperatures in Portable Liquid Cylinders (PLC).
WARNING
Extreme Cold
Contact with the super-cold liquid, gas or pipe surfaces can cause severe
skin damage. The Portable Liquid Cylinders should be located in a shielded
position, and all piping should be routed or covered to prevent skin contact.
For high gas flow rates and/or low ambient temperatures, it may be
necessary to obtain sufficient gas pressure by passing the liquid
through an external evaporator rather than use the internal pressure
building facility of the PLCs.
Liquid argon and liquid nitrogen may not be stored for extended
periods and often have special storage requirements. Contact your
local authorities and cryogenic gas supplier for more detailed
information on storage requirements and boil-off rates for local types
of PLCs.
After the gas requirements have been met, check the checklist box: Gas supply (at
specified purity), regulator, and gas lines are installed for argon and optional nitrogen.
Water Chiller System
Agilent ICP-OES instruments require a source of cooling water. The
water chiller system needs to remove up to 1400 W. The cooling
water is required for the Solid State RF oscillator, load coil, camera
Peltier assembly and Axial sample cone interface. The instrument
incorporates an in-line particulate filter and water flow sensors on
the water supply line.
