Introduction

Important Safety Warnings

Before moving on, there are several important safety notices that you
should always keep in mind when using the Agilent 7820A GC.
When handling/using chemicals for preparation or use within the GC, all applicable
WA R N I N G
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.
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
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 (oven, detector, inlet, or valve box).
All these parts are shielded by covers. With the covers in place, it should be difficult
WA R N I N G
to accidentally make contact with dangerous voltages. Unless specifically
instructed to, never remove a cover unless the detector, inlet, or oven are turned off.
If the power cord insulation is frayed or worn, the cord must be replaced. Contact
WA R N I N G
your Agilent service representative.
