General
Operation of an Agilent 710/715/720/725 Series ICP Optical
Emission Spectrometer involves the use of compressed gases, high
voltage radio frequency energy and hazardous materials including
corrosive fluids and flammable liquids. Careless, improper or
unskilled use of this spectrometer can cause death or serious injury
to personnel, and/or severe damage to equipment and property.
The spectrometer incorporates interlocks and covers that are
designed to prevent inadvertent contact with any potential hazards.
If the instrument is used in any manner not specified by Agilent, this
protection provided by the equipment may be impaired. It is good
practice to develop safe working habits that do not depend upon the
correct operation of the interlocks for safe operation. It is essential
that no interlock or cover is bypassed, damaged or removed.

Safety Practices and Hazards
8 Agilent 700 Series ICP Optical Emission Spectrometers User’s Guide
The safety practices described below are provided to help the user
operate the instrument safely. Read each safety topic thoroughly
before attempting to operate the instrument and always operate the
spectrometer in accordance with these safety practices.
Plasma
The plasma is extremely hot (about 10,000 K) and radiates dangerous
levels of radio frequency (RF) and ultraviolet (UV) energy. The work
coil operates at 1,500 V RMS and about 40 MHz. Exposure to the RF
and UV energy can cause severe skin damage and cataracts of the
eyes, while close contact with the operating plasma can result in
severe heat burns to the skin, and an electrical discharge that can
jump a considerable distance and may cause death, severe electric
shock or sub-surface skin burns.
The plasma must never be operated unless:
the torch compartment door is closed, with the locking lever fully
latched; and
the space above the chimney is clear of objects.
The shielding around the torch compartment is designed to reduce
UV, visible and RF radiation to safe levels while still permitting easy
access to, as well as installation and viewing of, the torch. The
spectrometer has an interlock system that is designed to extinguish
the plasma if either the mains supply fails or the handle on the torch
compartment door is opened. Do not attempt to bypass the interlock
system.
Before opening the torch compartment door, always extinguish the
plasma by pressing F4 on the keyboard or by clicking the ‘Plasma Off’
icon on the ICP Expert II software toolbar.
The torch and its surroundings remain hot for up to five minutes
after the plasma is extinguished. Touching this area before it has
cooled sufficiently may result in burns. Allow the torch and torch
compartment to cool before carrying out any work in this area, or
wear heat-resistant gloves.

Safety Practices and Hazards
Agilent 700 Series ICP Optical Emission Spectrometers User’s Guide 9
The plasma system has been carefully designed to operate safely and
effectively when using torches and related components that conform
to Agilent’s design criteria. Use of non-approved components in the
plasma compartment may render the system inoperative and/or
hazardous. It may also invalidate the warranty on the instrument.
Use only torches and related components supplied or authorized by
Agilent.
Heat, Vapors and Fumes
Heat, ozone, vapors and fumes generated by the plasma can be
hazardous, and must be extracted from the instrument by means of
an exhaust system. Ensure that an exhaust system of the appropriate
type is fitted (as specified in the Site Preparation Guide). The system
must be vented to the outside air in accordance with local regulations
and never within the building. Regularly check the exhaust system by
smoke test to ensure that the exhaust system is functioning correctly.
The exhaust fan must always be switched on before igniting the
plasma.
Compressed Gas Hazards
All compressed gases (other than air) can create a hazard if they leak
into the atmosphere. Even small leaks in gas supply systems can be
dangerous. Any leak (except that of air) can result in an oxygen-
deficient atmosphere, which can cause asphyxiation. The area in
which cylinders are stored and the area surrounding the instrument
must be adequately ventilated to prevent such gas accumulations.
Gas cylinders must be stored and handled strictly in accordance with
local safety codes and regulations. Cylinders must be used and stored
only in a vertical position and secured to an immovable structure or
a properly constructed cylinder stand. Move cylinders only by
securing them to a properly constructed trolley.
Use only approved regulator and hose connectors (refer to the gas
supplier’s instructions). Keep gas cylinders cool and properly
labeled. (All cylinders are fitted with a pressure relief device that will
rupture and empty the cylinder if the internal pressure is raised
above the safe limit by excessive temperatures.) Ensure that you have
the correct cylinder before connecting it to the instrument.

Safety Practices and Hazards
10 Agilent 700 Series ICP Optical Emission Spectrometers User’s Guide
The primary gas to be used with the spectrometer is argon, which is
the conductive gas for the plasma. Argon or nitrogen can be used as
the polychromator purge gas. Other gases may be required for future
options and accessories. Use only ‘instrument grade’ gases with your
spectrometer.
If using cryogenic gases (for example, liquid argon), prevent severe
burns by wearing suitable protective clothing and gloves.
Electrical Hazards
The spectrometer system and some accessories contain electrical
circuits, devices and components operating at dangerous voltages.
Contact with these circuits, devices and components can cause death,
serious injury or painful electric shock. Panels or covers which are
retained by screws on the spectrometer and accessories may be
opened only by Agilenttrained, Agilent-qualified or Agilentapproved
field service engineers (unless specified otherwise). Consult the
manuals or product labels supplied with your personal computer
(PC), monitor, printer and water-cooling system to determine which
parts are operator-accessible.
Replace blown fuses with ones of the size and rating shown in the
text near to the fuse holder.
Other Precautions
Use of the spectrometer system and accessories may involve
materials, solvents and solutions which are flammable, corrosive,
toxic or otherwise hazardous. Careless, improper or unskilled use of
such materials, solvents and solutions can create explosion hazards,
fire hazards, toxicity and other hazards that can result in death,
serious personal injury or damage to equipment.
Operation of an ICP-OES involves analysis of solutions that have
been prepared in or digested with acids, or in some cases, samples
that have been prepared in organic solvents.
