GC Safety Manual
Important Safety Warnings
Before moving on, there are several important safety notices that you should always keep in
mind when using the Agilent Agilent 8890.
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, using
vent hoods, 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.
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, the AC power supply
itself, and the wiring from the AC power supply to the power switch.
With the power switch on, potentially dangerous voltages also exist on:
•
All electronics boards in the instrument.
•
The internal wires and cables connected to these boards.
•
The wires for the oven heater.
WARNING
All these parts are shielded by covers. With the covers in place, it should be difficult to
accidentally make contact with dangerous voltages. Unless specifically instructed to, never
remove a cover unless the instrument is unplugged.
WARNING
If the power cord insulation is frayed or worn, the cord must be replaced. Contact your Agilent
service representative.

Introduction
Lifting
GC Safety Manual
5
Lifting
WARNING
The GC is heavy. To avoid injury, use a two–person lift.
CAUTION
Make sure that all samplers, trays, and detectors have been removed prior to moving or
relocating the GC. Prior to moving, all covers and enclosures must also be seated properly.
Make sure all covers and enclosures are secure.
CAUTION
Make sure your GC has adequate distance from the wall and other instruments.
Do not use an Uninterruptable Power Supply (UPS)
with a GC
If the area where the GC is located suddenly loses power, an unsafe condition can result if the
GC remains powered on. Do not use the GC with a UPS.
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.

Introduction
Many parts are dangerously hot
6
GC Safety Manual
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 inlet area
•
The oven and its contents
•
The detector area
•
The column nuts 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 instrument part that you will be maintaining before you begin
working on it. Do not open the oven door immediately after the heating sequence.
WARNING
Be careful when working behind the instrument. During cool-down cycles, the GC emits hot
exhaust which can cause burns.
WARNING
The insulation around the inlets, detectors, valve box, and the insulation cups is made of
refractory ceramic fibers. To avoid inhaling fiber particles, we recommend the following
safety procedures: ventilate your work area; wear long sleeves, gloves, safety glasses, and a
disposable dust/mist respirator; dispose of insulation in a sealed plastic bag; wash your
hands with mild soap and cold water after handling the insulation.
Oven thermal leaks
WARNING
Objects passing through the oven door seal can cause thermal leaks which create hazardous
hot spots which cause burns and melt equipment.
Do not allow wiring or temperature probes to pass through the oven door jam. Agilent
recommends using one of the access holes. If the access hole is used, replace the insulation
so there are no thermal leaks.

Introduction
Hydrogen Safety
GC Safety Manual
7
Hydrogen Safety
Hydrogen gas may be used as carrier gas, and/or as fuel for the FID, FPD, NPD, NCD, and SCD.
When mixed with air, hydrogen can form explosive mixtures.
WARNING
When using hydrogen (H2) as the carrier gas or fuel gas, be aware that hydrogen gas can flow
into the GC oven and create an explosion hazard. Therefore, be sure that the supply is turned
off until all connections are made and ensure that the inlet and detector column fittings are
either connected to a column or capped at all times when hydrogen gas is supplied to the
instrument.
Hydrogen is flammable. Leaks, when confined in an enclosed space, 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.
Hydrogen is a commonly used GC carrier gas. Hydrogen is potentially explosive and has other
dangerous characteristics.
•
Hydrogen is combustible over a wide range of concentrations. At atmospheric pressure,
hydrogen is combustible 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 explosive mixtures.
The GC monitors inlet, detector, 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 split valves in the inlets open.
•
The oven (heater and fan) turns off.
•
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.

Introduction
Measuring hydrogen gas flows
8
GC Safety Manual
WARNING
The GC cannot always detect small 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 H2 streams must be configured for hydrogen so that the GC is
aware of hydrogen use.
Measuring hydrogen gas flows
WARNING
Do not measure hydrogen together with air or oxygen. This can create explosive mixtures
that can be ignited by the automatic ignitor.
To avoid this hazard turn the automatic ignitor off before you begin, and always measure
gases separately.
Fume Hood
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
Electron Capture Detector (ECD)
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 450 °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.
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 the four socket-head bolts is a violation of the
terms of the exemption and could create a safety hazard.
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.

Introduction
Fuses and Batteries
10
GC Safety Manual
•
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.
Fuses and Batteries
The GC requires two fuses (F1, F2) for proper operation. The replacement fuses are
F1/F2-Ceramic body, 20 A, 250 V, Type F, but must only be accessed by Agilent trained service
personnel.
There is a Real Time Clock component on the Logic board that includes a battery inside.
WARNING
Disconnect the appliance inlet coupler from the main supply before replacing the fuses.
Disconnect Device
WARNING
Appliance inlet coupler (main input power cord) is the power disconnect device. Do not
position the instrument such that access to the coupler or plug is impaired.
WARNING
The front power switch does not disconnect power for the instrument. Pressing the
disconnect switch places the instrument in a standby mode. To avoid an electric shock
hazard, disconnect the device by unplugging the power cord before performing instrument
service.
