Mini Thermal Desorber Safety

WARNING

When handling/using chemicals for preparation or use within the
instrument, 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

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
when instrument is in operation

WARNING

If the power cord insulation is frayed or worn, the cord must be
replaced. Contact your Agilent service representative.

Important Safety Warnings

Before moving on, there are several important safety notices that
you should always keep in mind when using the Agilent 7667A Mini
Thermal Desorber.

If the instrument is connected to a power source, even if the power
switch is off, potentially dangerous voltages exist on:

 The wiring between the instrument 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, AC/DC Adaptor also exists potentially

dangerous voltages.

Mini Thermal Desorber Safety

警告

This is a Safety Class 1 Product (provided with a protective earthing
ground, incorporated in the AC/DC Adaptor). The mains plug shall
only be inserted in a socket outlet provided with a protective earth
contact. Any interruption of the protective conductor inside or outside
of the instrument is likely to make the instrument dangerous.
Intentional interruption is prohibited.

WARNING

Be careful when using instrument, During cool-down cycles, the
instrument emits hot exhaust which can cause burns.

Do not tamper with protective earth ground

Do not use an Uninterruptable Power Supply (UPS) with a Mini TD

If the area where the instrument is located suddenly looses power, an
unsafe condition can result if the instrument remains powered on. Do
not use the instrument with a UPS.

Electrostatic discharge is a threat to instrument electronics

The printed circuit (PC) boards in the instrument 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 any instrument cover.

Many parts are dangerously hot

Many parts of the instrument operate at temperatures high enough to
cause serious burns. These parts include but are not limited to:

 6-port diaphragm valve
 Transfer line
 Tube

You should always cool these areas of the instrument to room
temperature before working on them. First set temperature 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.。

Mini Thermal Desorber Safety

Never use a flammable gas for vial pressurization

General gas safety

Flammable gases, such as hydrogen and argon/methane, create a
potential explosion hazard during vial pressurization and inventing.
The Agilent 7667A Mini Thermal Desorber cannot be configured to
use a flammable gas for vial pressurization.

 Wear eye protection when using compressed gas to avoid eye

injury.

 Fasten all compressed gas cylinders securely to an immovable

structure or permanent wall.

 Store and handle compressed gases in accordance with relevant

safety codes.

 Do not put gas cylinders in the path of a hot air vent (the

exhaust emission by instrument).

General warnings

 Perform periodic leak checks on supply lines, fittings, and

 To avoid a potential shock hazard when using liquid solution to

Use with chemicals

When handling/using chemicals for preparation or use within the
instrument, follow all applicable local and national laboratory safety
practices. This includes, 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.

Hydrogen Safety

Dangers unique to GC and GC/MSD operation

Hydrogen presents a number of dangers. Some are general; others are
unique to GC or GC/MS operation. Dangers include, but are not
limited to:

 Combustion of leaking hydrogen.
Combustion due to rapid expansion of hydrogen from a high-

pressure cylinder..

Batteries

Accumulation of hydrogen in the GC oven and subsequent
combustion (see your GC documentation and the label on the top
edge of the GC oven door).

Accumulation of hydrogen in the MSD and subsequent combustion.

The instrument requires fuses and batteries for proper operation.
These must only be accessed by Agilent trained service personnel.
