This section provides information on how to identify
specifically what type of MSD you are working with as well as
how to properly clean and dispose of the instrument. Also
included in this section are the “Important Safety Warnings”
which list critical safety precautions for all users.

General Information
Instrument Identification
Each 5973N and 5973 inert Mass Selective Detector (MSD) is
identified by a unique 10-character serial number. This serial
number is located on a label on the lower left side near the front
of the instrument. On CI upgrades, a serial number is located on
the flow module.
When corresponding with Agilent Technologies about your
instrument, be sure to include the model number and both full
10-character serial numbers.
Write the serial number of your 5973 MSD here for reference:
5973N MSD version
The 5973N MSD is equipped with a diffusion pump. The serial
number label displays a product number that tells what kind of
MSD you have:
5973 inert MSD version
The 5973 inert MSD is equipped with either a standard
turbomolecular pump or a performance turbomolecular pump.
Chemical Ionization is available for the turbo MSDs only. The
serial number label displays a product number that tells what
kind of MSD you have:
This site preparation guide will refer to both 5973N and
5973 inert MSDs as 5973 Series MSDs unless noted otherwise.

Important Safety Warnings
Before moving on, there are several important safety notices
that you should always keep in mind when using the 5973 Series
Mass Selective Detector.
Many internal parts of the MSD carry dangerous voltages
If the MSD is connected to a power source, even if the power
switch is off, potentially dangerous voltages exist on:
•The wiring between the MSD 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 any heater.
Connecting the MSD to power sources that are not equipped
with protective earth contacts creates a shock hazard for the
operator and can damage the instrument.
Interrupting the protective conductor inside or outside the MSD
or disconnecting the protective earth terminal creates a shock
hazard for the operator and can damage the instrument.
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 detector, inlet, or oven are turned off.
WARNING If the power cord insulation is frayed or worn, the cord must be
replaced. Contact your Agilent service representative.

8Site Preparation Guide
General Information
Make sure the power cords supplied with the MSD are
appropriate for your country and site before using them.
Maintain easy access to the power cords so they can be
disconnected during maintenance.
The use of incorrect or makeshift fuses or the short-circuiting of
fuse holders creates a shock hazard for the operator and can
damage the instrument. Replace fuses only with fuses of
identical current rating and type.
Excessive fluctuations in the line voltage can create a shock
hazard and can damage the instrument. Make sure the supply
voltage does not fluctuate more than +5% or -10% from the rated
voltage. This equipment must be installed in a Category II
environment as defined in IEC 664.
Electrostatic discharge is a threat to MSD electronics
The printed circuit (PC) boards in the MSD 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 MSD
covers.
Many parts are dangerously hot
Many parts of the MSD operate at temperatures high enough to
cause serious burns.
You should always cool heated areas of the MSD 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 gloves. Whenever possible, cool the part of the
instrument that you will be maintaining before you begin
working on it.

General Information
Site Preparation Guide 9
Hydrogen
Hydrogen gas may be used as carrier gas, and/or as fuel for an
FID. When mixed with air, hydrogen can form explosive
mixtures.
WARNING Be careful when working behind the gas chromatograph (GC).
During cool-down cycles, the GC emits hot exhaust which can cause
burns.
WARNING The insulation around the GC 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.
WARNING When using hydrogen (H2) as the carrier gas or fuel gas, be aware
that hydrogen gas can flow into the oven and create an explosion
hazard. Therefore, be sure that the supply is off until all connections
are made, and ensure that the GC 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 or explosion 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.
WARNING The MSD cannot detect leaks in 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.

10 Site Preparation Guide
General Information
When using hydrogen gas, check the system for leaks as
described by your local Environmental Health and Safety (EHS)
requirements to prevent possible fire and explosion hazards.
Always check for leaks after changing a tank or servicing the
gas lines. Always make sure the vent line is vented into a fume
hood.
Chemical safety
WARNING The foreline pump exhaust and split vent exhaust will contain traces
of the chemicals you are analyzing. These could potentially be toxic.
Vent the foreline pump exhaust and split vent exhaust outside your
laboratory or into a fume hood. Be sure to comply with all local
environmental regulations.
