The printed circuit (PC) boards in the detector 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, or the right or left side detector covers.
Many parts of the detector operate at temperatures high enough
to cause serious burns. These parts include, but are not limited
to:
• The dual plasma burner
• The detector interface to the GC, including the column
connection
Always cool these areas of the detector to room temperature
before working on them. 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.
Hydrogen gas is used as a fuel gas to produce a flame in the
detector.
When using hydrogen (H
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 detector column
fittings are either connected to a column or capped at all times
when hydrogen gas is supplied to the detector. 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.
