Introduction
Important Safety Warnings
Before moving on, there are several important safety notices that you should
always keep in mind when using the Agilent GC.
Many internal parts of the GC carry dangerous voltages
If the GC is connected to a power source, even if the power switch is off,
potentially dangerous voltages exist on:
•The wiring between the GC power cord and the AC power supply and the
AC power supply itself.
Do not use an Uninterruptable Power Supply (UPS) with a GC
If the area where the GC is located suddenly looses power, an unsafe condition
can result if the GC remains powered on. Do not use the GC with a UPS.
WARNING
When handling/using chemicals for preparation or use within the GC, all
applicable local and national laboratory safety practices must be followed. This
would include, but is not limited to, correct use of Personal Protective Equipment
(PPE), correct use of storage vials, and correct handling of chemicals, as defined in
the laboratory’s internal safety analysis and standard operating procedures. Failure
to adhere to laboratory safety practices could lead to injury or death.
WARNING
If the power cord insulation is frayed or worn, the cord must be replaced. Contact
your Agilent service representative.
WARNING
The GC power supply uses double pole/neutral fusing. Line voltage can be present
on the neutral and on the phased power leads. To prevent electric shock, always
disconnect the power cord before servicing the instrument. Refer servicing to
Agilent-trained personnel only. There are no user serviceable parts within the GC
power supply.

Introduction
Intuvo 9000 GC Safety Manual 5
Electrostatic discharge is a threat to GC electronics
The printed circuit (PC) boards in the GC can be damaged by electrostatic
discharge. Do not touch any of the boards unless it is absolutely necessary. If
you must handle them, wear a grounded wrist strap and take other antistatic
precautions. Wear a grounded wrist strap any time you must remove the GC
right side cover.
Many parts are dangerously hot
Many parts of the GC operate at temperatures high enough to cause serious
burns. These parts include but are not limited to:
•The inlets
•The detectors
•The attaching the column to an inlet or detector
•The valve box
You should always cool these areas of the GC to room temperature before
working on them. They will cool faster if you first set the temperature of the
heated zone to room temperature. Turn the zone off after it has reached the
setpoint. If you must perform maintenance on hot parts, use a wrench and
wear thermally protective gloves. Whenever possible, cool the part of the
instrument that you will be maintaining before you begin working on it.
WARNING
Be careful when working behind the instrument. During cool-down cycles, the GC
emits hot exhaust which can cause burns.

Introduction
Hydrogen Safety
Hydrogen gas may be used as carrier gas, and/or as fuel for the FID and NPD.
When mixed with air, hydrogen can form fire hazard.
Hydrogen is a commonly used GC carrier gas. Hydrogen is potentially a fire
hazard and has other dangerous characteristics.
•Hydrogen is a fire hazard over a wide range of concentrations. At
atmospheric pressure, hydrogen is a fire hazard at concentrations from 4%
to 74.2% by volume.
•Hydrogen has the highest burning velocity of any gas.
•Hydrogen has a very low ignition energy.
•Hydrogen that is allowed to expand rapidly from high pressure into the
atmosphere can self-ignite due to an electrostatic spark.
•Hydrogen burns with a nonluminous flame which can be invisible under
bright light.
Hydrogen shutdown
Hydrogen gas may be used as a carrier or as fuel for some detectors. When
mixed with air, hydrogen can form fire hazard.
The GC monitors inlet and auxiliary gas streams. If a stream shuts down
because it is unable to reach its flow or pressure setpoint and if that stream is
configured to use hydrogen, the GC assumes that a leak has occurred and
declares a hydrogen safety shutdown. The effects are:
•The offending channel and any associated channels (such as septum purge)
are set off.
•The column heater turns off.
WARNING
Hydrogen is flammable. Leaks may create a fire hazard. In any application using
hydrogen, leak test all connections, lines, and valves before operating the
instrument. Always turn off the hydrogen supply at its source before working on the
instrument.

Introduction
Intuvo 9000 GC Safety Manual 7
•The small heated zones are turned off.
•An alarm tone sounds.
To recover from this state, fix the cause of the shutdown (tank valve closed,
serious leak, others). Turn the instrument off, then back on.
Measuring hydrogen gas flows
When measuring gas flows on a detector using hydrogen for the detector flame
or carrier gas, measure the hydrogen flow separately. Never allow an air
stream to enter when hydrogen is present in the flow meter.
WARNING
The GC cannot always detect leaks in inlet and/or detector gas streams. For this
reason, it is vital that column fittings should always be either connected to a
column, or have a cap or plug installed. The H2streams must be configured for
hydrogen so that the GC is aware of hydrogen use.
WARNING
Do not measure hydrogen together with air or oxygen. This can create explosive
mixtures that may be ignited by the automatic ignitor.
To avoid this hazard:
Turn the automatic ignitor off before you begin.
Always measure gases separately.

Introduction
Uncombusted Hazardous Gases
During normal operation of the GC with many detectors and inlets, some of
the carrier gas and sample vents outside the instrument through the split vent,
septum purge vent, and detector exhaust. If any sample components are toxic
or noxious, or if hydrogen is used as the carrier gas, these exhausts must be
vented to a fume hood. Place the GC in the hood or attach a large diameter
venting tube to the outlet for proper ventilation.

Introduction
Intuvo 9000 GC Safety Manual 9
Electron Capture Detector (ECD)
The ECD contains a cell plated with 63Ni, a radioactive isotope. The beta
particles released at the energy level in the detector have little penetrating
power—the surface layer of the skin or a few sheets of paper will stop most of
them—but they may be hazardous if the isotope is ingested or inhaled. For this
reason, handle the cell with care. Cap the detector inlet and outlet fittings
when the detector is not in use. Never introduce corrosive chemicals into the
detector. Vent detector exhaust outside the laboratory environment.
Refer to the safety documentation provided with the detector for important
details about safety, maintenance, and compliance with local government
regulation.
WARNING
Materials that may react with the 63Ni source, either to form volatile products or to
cause physical degradation of the plated film, must be avoided. These materials
include oxidizing compounds, acids, wet halogens, wet nitric acid, ammonium
hydroxide, hydrogen sulfide, PCPs, and carbon monoxide. This list is not exhaustive
but indicates the kinds of compounds that may cause damage to 63Ni detectors.
WARNING
In the extremely unlikely event that the oven or the detector-heated zone should go
into thermal runaway (maximum, uncontrolled heating in excess of 400 °C) and the
detector remains exposed to this condition for more than 12 hours, take the
following steps:
1 After turning off the main power and allowing the instrument to cool to room
temperature, cap the detector inlet and exhaust vent openings. Wear disposable
plastic gloves and observe normal laboratory safety precautions.
2 Contact your local Agilent Technologies sales office or distributor for ECD disposal
instructions
3 Include a letter stating the condition of abuse.
It is unlikely, even in this very unusual situation, that radioactive material will
escape the cell. However, permanent damage to the 63Ni plating within the cell is
possible; therefore, the cell must be returned for exchange.

Introduction
When handling ECDs:
•Never eat, drink, or smoke.
•Always wear safety glasses when working with or near open ECDs.
•Wear protective clothing such as laboratory jackets, safety glasses, and
gloves, and follow good laboratory practices. Wash hands thoroughly with a
mild nonabrasive cleaner after handling ECDs.
•Cap the inlet and outlet fittings when the ECD is not in use.
•Connect the ECD exhaust vent to a fume hood or vent it to the outside. See
the latest revision of 10 CFR Part 20 (including Appendix B), or the
applicable state regulation. For other countries, consult with the
appropriate agency for equivalent requirements.
Agilent Technologies recommends a vent line internal diameter of 6 mm
(1/4-inch) or greater. With a line of this diameter, the length is not critical.
WARNING
Do not use solvents to clean the ECD.
WARNING
You may not open the ECD cell unless authorized to do so by your local nuclear
regulatory agency. Do not disturb the four socket-head bolts. These hold the cell
halves together. United States customers removing or disturbing them is a violation
of the terms of the exemption and could create a safety hazard.
