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.

6Site Preparation Guide

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.

General Information

Site Preparation Guide 7

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.
