General Maintenance
Some procedures in this chapter require access to the inside of the GC/MSD
while the power switch is on. Do not remove any of the electronics safety
covers in any of these procedures. To reduce the risk of electric shock, follow
the procedures carefully.
Dangerous temperatures
Many parts in the instrument operate at, or reach, temperatures high enough
to cause serious burns. These parts include, but are not limited to:
• GC/MSD interface
• Analyzer parts
• Vacuum pumps
• Inlet
• LTM column
• Guard column heated enclosure
Never touch these parts while your instrument is on. After the instrument is turned
WA R N I N G
off, give these parts enough time to cool before handling them.
The foreline pump can cause burns if touched when operating.
WA R N I N G
The inlet, guard column heated enclosure, and LTM column also operate at
very high temperatures. Use the same caution around these parts.
Chemical residue
The split vent outlet and purge vent outlet contain high concentrations of the
chemicals you are analyzing along with the carrier gas. If you are processing
hazardous chemicals, these outlets should be vented to a safe location outside
the laboratory.
