Introduction
18 Agilent 5800 and 5900 ICP-OES User's Guide
Water Chiller System
Agilent ICP-OES instruments require a source of cooling water. Refer to the Site
Preparation Guide for compatible water chilling systems and to the documentation
provided with the water chilling system for installation and use instructions.
NOTE
Pressure regulation is recommended for supplies where the cooling water
pressure may be subject to fluctuations. Pressure regulation is necessary for
supplies that may exceed the maximum permissible pressure of 400 kPa (58 psi).
The instrument is equipped with a water flow sensor, which will stop operation of the
plasma if the cooling water flow through the instrument drops below 1.7 L/min (0.45
gpm). A second water flow sensor will stop the camera Peltier cooling assembly if the
water flow through the instrument drops below 0.2 L/min (0.05 gpm).
CAUTION
Always ensure the water chillersystem is on before igniting the plasma.
Drain Vessel
The Agilent ICP-OES system needs a drain vessel for disposal of excess fluids
from the spray chamber or autosampler. Suitable tubing is supplied with the
spectrometer for use with inorganic solvents. When using organic solvents,
different drain tubing that is suitable for the solvent in use will be required.
A chemically inert container, not glass or of a narrow-necked style, to hold a
minimum of 2 liters (4 pints) of waste must be provided by the user. It should be
located underneath the sample compartment (or on the right side of the
instrument), where it is protected by the bench and in full view of the operator.
